What are the organisms at the beginning of a food chain? The organisms at the beginning of the food chain are called producers or autotrophs, such as plants and algae. Some make their own food using the sun's energy through photosynthesis and some producers use chemosynthesis to make their own food. Above them would be 1st level consumers, then 2nd level consumers and so on.

Food web All species in the food webs can be distinguished into basal species (autotrophs, such as plants), intermediate species (herbivores and intermediate level carnivores, such as grasshopper and scorpion) or top predators (high level carnivores such as fox) (Figure 1).n a detrital food chain, dead organic matter of plants and animals is broken down by decomposers, e.g., bacteria and fungi, and moves to detritivores and then carnivores. Food web offers an important tool for investigating the ecological interactions that define energy flows and predator-prey relationship (Cain et al.

Consumer (food chain) Within an ecological food chain, consumers are categorized into three groups: primary consumers, secondary consumers, and the tertiary consumers. Primary consumers are usually herbivores, feeding on plants and fungus. Secondary consumers, on the other hand, are mainly carnivores, and prey on other animals.

Food Chains and Webs The next level in the food chain is made up of primary consumers, or organisms that eat food produced by other organisms. Examples of primary consumers include zooplankton, ducks, tadpoles, mayfly nymphs and small crustaceans. Secondary Consumers Secondary consumers make up the third level of the food chain. Secondary consumers feed on smaller, plant-eating animals (primary consumers). Examples of secondary consumers include bluegill, small fish, crayfish and frogs.

What Are the Different Types of Phytoplankton? Diatoms, dinoflagellates and microflagellates form the bottom of the aquatic food chain. Numbers of phytoplankton in an ocean might be so concentrated that they affect the color of the water and tint the water brown, green or red. Phytoplankton provide a necessary part of the aquatic food chain.

What is food chain? A food chain is the flow of energy from one organism to the next. Organisms in a food chain are grouped into trophic levels — from the Greek word for nourishment, trophikos — based on how many links they are removed from the primary producers. food chain is what is it called......a food chain usually contains a producer,consumer,carnivore,and an omnivore.....an example of a food chain like this is GRASS(PRODUCER),RABBIT(CONSUMER),FOX(CAR... i hope this helps....

- Producers and consumers. A food chain always starts with a producer, which is an organism that makes food. This is usually a green plant, because plants can make their own food by photosynthesis. A food chain ends with a consumer, which is an animal that eats a plant or another animal.

Organisms at the base of the food web are called? Best Answer: On a food pyramid, the first trophic level is made up of autotrophs (organisms capable of creating their own food). These are usually called producers.Above the producers are the primary consumers (usually herbivores such as deer). Above the Primary consumers are the Secondary consumers that eat the secondary consumers (such as wolves that eat the deer). Above that are the tertiary consumers that are at the top of the food chain.est Answer: On a food pyramid, the first trophic level is made up of autotrophs (organisms capable of creating their own food).

Food Chains and Webs Food Chains. 1  Producers. Plants form the base of Great Lakes food chains. They’re called producers, because they make their own food by converting sunlight through photosynthesis. They also act as food, providing energy for other organisms. In the Great Lakes, most producers are phytoplankton, or microscopic floating plants. An example of phytoplankton is green algae. Large rooted plants, another type of producer, provide food and shelter for different organisms, fish and wildlife.

Secondary consumers feed on smaller, plant-eating animals (primary consumers). Examples of secondary consumers include bluegill, small fish, crayfish and frogs. Top Predators Top predators are at the top of the food chain. Top predators eat plants, primary consumers and/or secondary consumers. They can be carnivores or omnivores. Top predators typically sit atop the food chain without predators of their own. Examples include fish such as lake trout, walleye, pike and bass, birds such as herons, gulls and red tailed hawks, bears—and humans! Food Webs

blog Carnivores, Carnivora, and Frugivorous Carnivorans. The term “carnivore” is one that is best defined by a simple food web: at the base (first trophic level) of the food web are the producers: plants. The second trophic level are animals that eat plants – they are called primary consumers or herbivores.

food web All of the interconnected and overlapping food chains in an ecosystem make up a food web. Trophic Levels. Organisms in food webs are grouped into categories called trophic levels. Roughly speaking, these levels are divided into producers (first trophic level), consumers, and decomposers (last trophic level).

At which level of the food web is the supply of energy the greatest? explain? The first trophic level of the food chain has the greatest energy supply of food because they use the sun's energy to create their own food. (They are the autotrophs.) Organisms in other levels simply consume other organisms and obtain the energy through consumption.

Trophic level A food chain represents a succession of organisms that eat another organism and are, in turn, eaten themselves. The number of steps an organism is from the start of the chain is a measure of its trophic level.Food chains start at trophic level 1 with primary producers such as plants, move to herbivores at level 2, predators at level 3 and typically finish with carnivores or apex predators at level 4 or 5.The path along the chain can form either a one-way flow or a food web.ood chains start at trophic level 1 with primary producers such as plants, move to herbivores at level 2, predators at level 3 and typically finish with carnivores or apex predators at level 4 or 5.

Trophic Levels in a Food Chain: Definition & Explanation Primary producers are important to the whole food chain because they are the original source of energy that is then passed between other organisms. The next three trophic levels contain organisms known as consumers. Consumers are organisms that get their energy from eating other organisms.

- A food chain refers to four main parts. These are: * The sun – this is the primary source of energy for all organisms. * The producers – these are the plants. They are called producers because they are the only part of the food chain that produces their own food, as well as the food for other organisms. In fact, the oxygen that all living things breathe in is a result of the food producing process of the plants (photosynthesis).

- In this section we will discuss what is meant by food chains, food webs and ecological pyramids.The first trophic level is the producers, followed by the primary consumers, followed by the secondary, and finally, tertiary consumers. On the side of most energy-flow pyramids are the decomposers. I got this answer here!

- Three groups ofaquatic organisms include plankton, nekton, and benthos. Plankton are the organisms that float near the surface of the water. Two typesof plankton are microscopic plants called phytoplankton, and micro-scopic animals called zooplankton. Phytoplankton produce most ofthe food for an aquatic ecosystem. Nekton are free-swimming organ-isms, such as fish, turtles, and whales.
