Imagine a pond, a hectic pond where various organisms from phytoplankton, small fishes, big fishes, waterfowl, to snake and owl doing their daily business. Beside that in an ecotone that mark the transition between aquatic ecosystem with terestrial ecosystem, some other organisms including various species of plants and animals are joining the business. You may have seen that sort of pond somewhere, share that with me please …

Today,i have been given my first assigment for this subject for this semester.Hopefull,everything will be good.Straight to the point, I need to give
an opinions about what is the most important thing in the pond ecosystem that will support the survival of others species.
For me,the phytoplankton is the crucial species in the pond.First and foremost,let me explain a bit about what is the phytoplankton roughly(depends on my basic knowledge).Phytoplankton are the autotrophic component of the plankton community. Most phytoplankton are too small to be individually seen with the unaided eye. However, when present in high enough numbers, they may appear as a green discoloration of the water due to the presence of chlorophyll within their cells (although the actual color may vary with the species of phytoplankton present due to varying levels of chlorophyll or the presence of accessory pigments such as phycobiliproteins, xanthophylls.It can undergo photosynthesis process which will supply the oxygen gases to the others species in the pond.

The producer is the most important part of the food chain. The producers are autotrophic organisms. A producer is an organism capable of synthesizing its own organic substances from inorganic compounds. Autotrophs produce their own sugars, lipids, and amino acids using carbon dioxide as a source of carbon, and ammonia or nitrates as a source of nitrogen. Organisms that use light for the energy to synthesize organic compounds are called photosynthetic autotrophs; organisms that oxidize such compounds as hydrogen sulfide (H2S) to obtain energy are called chemosynthetic autotrophs, or chemotrophs. Photosynthetic autotrophs include the green plants, certain algae, and the pigmented sulfur bacteria. Chemotrophs include the iron bacteria, the nitrifying bacteria, and the nonpigmented sulfur bacteria. Heterotrophs are organisms that must obtain their energy from organic compounds. Phytoplankton and algae form the base of most freshwater food chains. It is often the case that biomass of each trophic level decreases from the base of the chain to the top. This is because energy is lost to the environment with each transfer. On average, only 10% of the organism’s energy is passed on to its predator. The other 90% is used for the organism’s life processes or it is lost as heat to the environment. Some producers, especially phytoplankton, are so productive and have such a high turnover rate that they can actually support a larger biomass of grazers. This is called an inverted pyramid, and can occur when consumers live longer and grow more slowly than the organisms they consume. The term phytoplankton encompasses all photoautotrophic microorganisms in aquatic food webs.

Food chains, also called, food networks and/or trophic social networks, describe the eating relationships between species within an ecosystem. Organisms are connected to the organisms they consume by lines representing the direction of organism or energy transfer. It also shows how the energy from the producer is given to the consumer.
Primary producer, commonly forming autotrophs, produce complex organic substances (essentially “food”) from an energy source and inorganic materials. These organisms are typically photosynthetic plants, which use sunlight as their energy source. A few, such as those organisms forming the base of deep-sea vent food webs, are chemotrophic, using chemical energy instead. Organisms that get their energy by organic substances are called heterotrophs. Heterotrophs include herbivores, which obtain their energy by consuming live plants; carnivores, which obtain energy from eating live animals; as well as detritivores, scavengers and decomposers, which all consume dead biomass. Energy enters the food chain from the sun. Some energy and/or biomass is lost at each stage of the food chain as; feces (solid waste), movement energy and heat energy (especially by warm-blooded creatures). Therefore, only a small amount of energy and biomass is incorporated into the consumer’s body and transferred to the next feeding level, thus showing a Pyramid of Biomass.
In my opinion, autotrophs or heterotrophs both is important in an ecosystem because even there is one changes in one of it the whole ecosystem while get disturb. For an example, in the pond if there is no big fishes there will too many small fishes. Besides that, there will too little phytoplankton in the pond as the amount of small fishes which are eating it is too much. Futhermore, when there is phytoplankton in the pond are less the living things inside will have a heard time to breath as they rely on the phytoplankton for air. This will destroy the whole ecosystem. So, as I said before all the living things in the ecosystem is important as its corelated to each other.

Food chains and food webs show the flow of energy through an ecosystem. Food webs are generally a more realistic portrayal of the energy flow in the system. After all, most organisms eat more than one type of food and can be eaten by more than one type of predator.
The fundamental energy source for most of the environment is the sun. Photoautotrophs are the most important role in food web because they capture the sun’s energy and use it to make organic compounds through photosynthesis. The process of photosynthesis transforms carbon dioxide and water into simple carbohydrates. The photoautotrophs then use the simple carbohydrates to build other more complex organic molecules (proteins, lipids and starches) that are either used as building blocks for their cells or are stored for later use. Photoautotrophs are often also called primary producers because they establish the basis for most other production; they create organic material from inorganic, or non-living, sources.
The food web you created in the food web game included producers and consumers, but it didn’t include all of the types of organisms that play a role in the food web. Decomposers also play an extremely important role in the food web. What are the decomposers? Bacteria! That’s right, just like the bacteria in every terrestrial environment, bacteria also live in the marine environment. And just like terrestrial bacteria, marine bacteria are EVERYWHERE and impact EVERYTHING! In their role as decomposers, they break down dead plant and animal matter and release simple molecules that can be absorbed and used by autotrophs and some heterotrophs. Bacteria play other roles in the marine environment as well. They are integral to nutrient cycling in the marine environment. Also, some bacteria are producers; they produce organic matter from inorganic matter through photosynthesis and chemosynthesis.

food chains and food webs is a complex chain of food flow network that starts from small plants that can produce food by their on to large animals.this food chains also playes a big role in ecosystem,
this food chain has a main producer that is sun, from sun the plants tht have cloroplas will produce food by the process of photosynthesis transforms carbon dioxide and water into sugar and energy..for an exp the phytoplankton.this phytoplankton will be eaten by fish..thn the fish will be eatan by owl…this is the cyle that will repead everyday…if let say fish is missing Freshwater fish introductions have the potential to alter competitive relationships among terrestrial plants, hampering the competitiveness of non-insect pollinated plants. Wetland destruction impacts dragonfly populations along with terrestrial plants. Polluted ponds and those that dry up at certain times of the year and those suffering from an excess of certain nutrients – a condition called eutrophication – all can harm fish abundances and insect-pollinated plants…

food chain is also known as a group of organisms interrelated by the fact that each member of the group feeds upon on the one below it and is in turn eaten by the organism above it in the chain. food chain can be defined as a feeding hierarchy in which organisms in an ecosystem are grouped into trophic (nutritional) levels and are shown in a succession to represent the flow of food energy and the feeding relationships between them. The directional flow of materials and energy from one organism to another is graphically represented by arrows. For example: trees and shrubs (producer) → giraffe (herbivore) → lion (carnivore).Most food chains have only about four to five links since too many links in a food chain will result in high demand, less supply of food (and therefore energy),this is a definition from the biology concept.
For this situation,the food chain begins with the phytoplankton, phytoplankton would be the producer in this food chain and would be in the base of the food triangle.they are consider as producers as they produce their own food by converting the sun lights energy during photosynthesis to produce their food. the 1st user or primer user will be the small fishes where they will consume phytoplankton as their food source and according to the energy trophic level,the fishes will obtain 10% energy from the phytoplankton.besides the small fishes would be heterotrophs as they consume organic substance to gain energy. the small fish would be prey from the big fishes which will act as the secunder user,these type of users ussually tend to be carnivours and they depend on their prey for food and energy. this chain continues from big fishes to waterfowl to snakes and ends at owl as the final user in this food chain.
these species on each other for their survival. for example, let say due to some problem such as there is no more big fishes,the pond will increase with the population of small fish and the waterfowl would being to reduce in population,as time passes this will cause to disorder in the population of species in the pond and in the end the food chain would be broken forever.
this is what we refer to habitat.in a habitat,there are other organism n different ecosystem going depending to each other.therefore,the food chain is very important,specially for organisms like in this pond situation.

Food chains are overly simplistic as representatives of what typically happens in nature. A food chain is the flow of energy from one organism to the next and to the next and so on. Organisms in a food chain are grouped into trophic levels, based on how many links they are removed from the primary producers.
Autotrophs are most important organism in food chain because they are fundamental to the food chains of all ecosystems.Furthemore,they are a vital part of the food chain Plants and other organisms that carry out photosynthesis are phototrophs (or photoautotrophs). Bacteria that utilize the oxidation of inorganic compounds such as hydrogen sulfide, ammonium or ferrous iron as an energy source are chemoautotrophs (some are known as lithotrophs)..They take energy from the environment in the form of sunlight or inorganic chemicals and use it to create energy-rich molecules such as carbohydrates. This mechanism is called primary production. Other organisms, called heterotrophs, take in autotrophs as food to carry out functions necessary for their life. Thus, heterotrophs ,all animals, almost all fungi, as well as most bacteria and protozoa depend on autotrophs for the energy and raw materials they need. Heterotrophs obtain energy by breaking down organic molecules (carbohydrates, fats, and proteins) obtained in food. Carnivorous organisms ultimately rely on autotrophs because the nutrients obtained from their heterotroph prey come from autotrophs they consumed.
Energy Flow Through these series of steps of eating and being eaten, energy flows from one trophic level to another. Green plants or other photosynthesizing organisms use light energy from the sun to manufacture carbohydrates for their own needs. Most of this chemical energy is processed in metabolism and dissipated as heat in respiration. Plants convert the remaining energy to biomass, both above ground as woody and herbaceous tissue and below ground as roots. Ultimately, this material, which is stored energy, is transferred to the second trophic level, which comprises grazing herbivores, decomposers, and detrital feeders. Most of the energy assimilated at the second trophic level is again lost as heat in respiration; a fraction becomes new biomass. Organisms in each trophic level pass on as biomass much less energy than they receive. Thus, the more steps between producer and final consumer, the less energy remains available. Seldom are there more than four links, or five levels, in a food web. Eventually, all energy flowing through the trophic levels is dissipated as heat. I feel, autrotroph is main important organism since it is fundamental to the food chain of all ecosystem.

A food chain is the sequence of who eats whom in a biological community (an ecosystem) to obtain nutrition. A network of many food chains is called a food web. The food chain starts with plants or other autotrophs – these organisms are called primary producers. The primary producers are eaten by herbivores (plant-eaters) called primary consumers. The herbivores are eaten by carnivores (meat-eaters) and omnivores (animals that eat both animals and plants) – these organisms are called secondary consumers. Secondary consumers may be eaten by other carnivores called tertiary consumers. When any organism dies, it is eaten by tiny microbes (detrivores) and the exchange of energy continues. Producers play the most important role in a food chain. A producer (or autotroph) is an organism that makes its own food from light energy (using photosynthesis), or chemical energy (using chemosynthesis). Most green plants, many protists (one-celled organisms like slime molds) and most bacteria are producers. Producers are the base of the food chain. Autotrophs are organisms that can “make their own food” from an inorganic source of carbon (carbon dioxide) given a source of energy. Most autotrophs use sunlight and chlorophyll in the process of photosynthesis to make their own food. Photosynthesis is the name of the process which autotrophs use to convert water, carbon dioxide, and solar energy into sugars and oxygen. Examples of autotrophs are plants, algae and cyanobacteria. These bacteria take energy from chemicals coming from the Earth’s interior and use it to make sugars. Other bacteria living deep underground can also produce sugars from such inorganic sources. Autotrophs provide food for the primary consumers, which are heterotrophs. Heterotrophs such as herbivores, omnivores, saprobes feed on autotrophs. The heterotrophs are in turn eaten by the secondary consumers, which are carnivores.

In a food chain, the most common, most dominant, and the most vital one will be the producer. In this case, the producer will be phytoplankton and green plants that involved in the food chain. A producer is an autotroph, which can make its own food. Producers form the first trophic level of a food chain, because they are the ones that produce usable energy for other species in the chain. They harness the Sun’s energy to make food by photosynthesis. They use energy from the sun to make sucrose, glucose, and other compounds that other life forms can eat and “burn” for energy. In each one of those sugar molecules a little bit of the sun’s energy is stored in a form that we can call chemical energy. Also, they take in carbon dioxide for their photosynthesis process, and give out oxygen in return. Oxygen is another essential element for the other living organisms to survive. Producers play a crucial role in converting raw energy to organic molecules and nutrients, which are useful to themselves and other organisms. Consumers capture these molecules by eating the producers, and use the nutrients they obtained to build organic tissue. Decomposers liberate nutrients from dead consumers and producers, and primary producers use these nutrients for growth. Without the producers, herbivors will not be able to live, that goes to carnivors too. Thus, in a very real way, it can be seen that without green plants and phytoplankton, no animals can survive in that food chain.

The producers is essential source for a food chain in an ecosystem. The producers are autotrophic organism. They are capable of producing their own organic substance from inorganic substance. Phytoplankton and algae are example of photosynthetic autotrophs.This are the crucial source in the pond and it is the base of the food chain.
The heterotrophs including herbivors feed on plants and carnivors feed on herbivors and it continous. The decomposers are also equaly important because they consume dead biomass.
The energy from the sun is also essential,on average only 10% of energy is passed on and the remaining is used by the organism itself.
Therefore I feel the energy from sun ,autotrophs, heterotrophs, and the decomposers are important in a food chain because it relies on each other.

What does the term “Food Chain” mean? According to the World Encyclopedia, “Food Chain” is defined as Transfer of energy through a series of organisms, each organism consuming the previous member of the chain. Its main sequence is from green plants (producers) to herbivores (the primary consumer) and then to the carnivores (the secondary consumer and finally to the decomposers like bacteria and fungi. The decomposers play a role whereby they break down the matters into forms that can be absorbed by plants, thus perpetuating the chains. From the question the most important class is the producers which are the phytoplankton and the green leafy plants. This is because they are able to produce their own food through chemosynthesis and photosynthesis. Producers are at the first tropic level. The photosynthesis is the process whereby the plants containing chlorophyll does the chemical process of converting the sun radiation energy to chemicals such as glucose and oxygen and water. Mostly they are autotrophic organisms at the first level of tropic level that is the producers. The rest at the food chain like the small fishes would be the primary consumer then the big fishes would be the secondary consumer as for the snake and the owl they are also the secondary consumers. Then finally will be the decomposes, are the decomposers.

Every living organism,from single cells to complex animals and plants,relies on its ecosystem to sustain life.An ecosystem consists of plants which act as producers,herbivores are the animals which only can consume plants,carnivores which can only eat meat,omnivores which eats both plant and animal and lastly decomposes such as fungi,where it decompose or renew the death organism.The most important interaction of organism are by way of a food chain.Each species in a food web obtain energy and chemicals for other organism.For example,rabbit eats plants,snake eats rabbit,eagle eats rabbit and lastly fungi in the soil decompose eagle and other organism when they die.and plants obtain vital nutrients from the soil.Indirectly the food chain is restarting from the plants which acts as producer.Besides it has the highest energy level in the pyramid of the food chain where the 10 percent of the energy consume by the decomposer.In my opinion the plants play the major role in the food chain cycle.

In an ecosystem, all producers and consumers mutually depend on and interact with one another through the food chain and food web. In reality, trophic activity relationships between individuals in a community are not as simple as shown by the food chains. This is because most animals use more than one species of organism as a food source. Thus, food chains do not exist in isolation but are interconnected with one another to form what is known as a food web, which is fairly complex. According to biology, the autotrophs comprise all photosynthesising plant that manufactures complex organic substances from simple inorganic substances through fixation of solar energy. As such, all autotrophs are producers. Also, heterotrophs comprise all animals and saprophytes which cannot manufacture their own food but are dependent on plants, whether directly or indirectly for their food. As such, all heterotrophs are consumers.
Sun is an important energy source in all ecosystems because all organisms functions such as growth and reproduction require energy. Energy moves through the ecosystem by a series of events that link organisms together. The producers are the necessary in the ecosystems because it produces oxygen and food needed by all other living things. Plants have green chemical called chlorophyll. Plants use chlorophyll to capture energy from the solar energy to split carbon oxide atoms. It will later on combine with the glucose ( C6H12O6) to make food. This process is known as photosynthesis. By this process, the solar energy from the sun is transformed into chemical energy. This process also releases oxygen as products. The plants use solar energy to produce food and that’s why they are at the first level in food chain and web cycle. The animals which are the consumers eat plants to produce energy for their cell functions. Those animals are called as primary consumers and they will release energy during respiration. Any compounds not used immediately are combines and stored as fats in the body. When the animals eaten by other animal, this composite are broken down and re-combined into new parts for the animals.
Consequently, all animals are depending on plants for food. These animals are known as secondary and tertiary consumers. Like herbivores, carnivores cannot obtain energy directly from the sunlight. Carnivores obtain their energy from energy-rich organic molecules in herbivores. Moreover, the omnivores also practice the same way of living as secondary animals. Furthermore, the decomposers such as bacteria and fungi live by obtaining energy-rich molecules from the tissues of dead producers and consumers. The tissues are converted back to simple compounds used by other plants. The food web cycle continues. From above, we can derive that plants are essential in food chain and web. As producers, it gives energy for all the animals from primary until tertiary levels. Without plants, there are no cycles involving transfer energy from one stage continues to the other stages.

The pond has it very own food chain.It basically begin with the producers such as the phytoplankton.The producer will be consume by the primary consumer that is the herbivores.The primary consumer acts as the energy source for the secondary consumer and the highest level of the pyramid food chain which is the ultimate predator.It consist of the carnivores or omnivores type of predator.Interestingly, the tertiary consumer consist only in small number compare with primary and secondary consumers respectively.The producers has the highest number and the only autotroph in the whole food chain.More over, they are the main source of energy.The energy cannot be destroy but being recycle throughout the chain. The decomposer play a vital part here as it complete the cycle.So, most of the energy is conserved wisely.
In every food chain,producers is the most important element cause it is the source of energy.This is because it can undergo the photosynthesus reaction that produce energy.So,phytoplankton can make a huge difference to the pond ecology system if it is decreased or uncreased in number.

Food chain is observed everywhere, even in the simplest habitat. The dependency relationship will continuously to exist for good. The links that connect the vastly found producer to the mighty top predator will move on smoothly based on the mutual relationship if there is no interruption.
The ecosystem has its own way to operate, and the key that holds to this thrives lies on the strong bonds between the producer, consumer, and the top predator. None of these component should be ignore nor to be eliminated. However, if you try to breakout the connection by taking out one component from this highly organised pyramid, the result will be a nightmare.
There will be no end if the is never a beginning. What makes the world stood as today is mainly because of the past history. Therefore, in a food chain the producer plays the most crucial character. If we need to consider where the producer gets the energy, then I should say that the sun is the most important.
In my opinion, the producer existence, such as the phytoplankton gives the biggest impact to the food chain. They manage to survive by interacting with the surroundings, by making use of the sunlight.
With their continuation, the primer consumer manages to flourish; become the food source of the secondary consumer while the tertiary consumer will consume the secondary consumer. Retarding the producer will destroy the food chain from the beginning. Larger damage will arise, thus resulted huge imbalance in the ecosystem.

As everyone knows, Ecosystems are dynamic interactions between plants, animals, and microorganisms and their environment working together as a functional unit. Ecosystems will fail if they do not remain in balance. Ecosystems vary in size. They can be as small as a puddle or as large as the Earth itself. Any group of living and nonliving things interacting with each other can be considered as an ecosystem. In my opinion I would say the most important role is carried by the producers. The producers can synthesize organic substances from inorganic compounds.In this ecosystem phytoplankton would be the producer in this food chain and would be in the base of the food triangle.they are consider as producers as they produce their own food by converting the sun lights energy during photosynthesis to produce their food. Then the phytoplankton is consumed by marine organism such as fishes shrimps and many others. As we all know, producers play a crucial role in converting raw energy to organic molecules and nutrients. Since producers are the main on the ecosystem other animals tend to depend on plants(producers) for food. These animals are known as secondary and tertiary consumers. The tertiary user in a pond would be the big fish. They would feed on smaller fishes, insects and many others. Ecosystem of a pond can be disturbed if one of these organisms are disturbed therefore, each organism has its own niche, or role, to play.

Food chain in a pond ecosystem is divided into three basic trophic levels, namely the first, second and third trophic levels. The first trophic level is represented by the producers or the autotrophs; for example, phytoplankton and plants. They prepare their own food with the help of energy from sunlight through the process of photosynthesis. The second trophic level is characterized by the herbivores such as insects, crustaceans and invertebrates inhabiting the pond and which consume the plants. The third and the topmost trophic level comprises of the carnivores, especially the fishes, which can feed on both plants and the herbivores of the first and second trophic level respectively.
In addition to the three trophic levels, there are saprotrophic organisms, commonly known as decomposers, which are located at the bottom of the food chain. Decomposers, mostly the bacteria and fungi are very important in the nutrient cycle as all the organic matter from the dead and decayed organisms is converted into carbon dioxide and nutrients such as nitrogen, phosphorus and magnesium. These nutrients are generated in such a way that they can be readily used by algae and plants for production of food to be consumed by the herbivores. Furthermore, the carnivores consume the producers and herbivores. Thus, the flow of energy is maintained in a pond ecosystem.
thank you…

The most important thing in the food chain would be the producer, as it is the one with the most in number. It manufactures complex organic substances from simple inorganic substances through fixation of solar energy. In the pond ecosystem, the phytoplankton would be most crucial. The primary consumer would feed on them, followed by the secondary consumer who feeds on the primary consumer, and so on. Every part of the food chain is dependent on each other. As the chain starts with the producer, a damage to phytoplankton would cause an imbalance in the pond ecosystem. Smaller fish would decrease in number, hence the number of bigger predator. A damage to the food chain means damage to the ecosystem. So without the phytoplankton, the pond ecosystem would diminish.
