Food Chain Definition Biology

A food chain usually starts with a photosynthetic plant which gains its energy from the Sun.

Food chain definition biology. What are food chains. What is a food chain. Shows what eats what in a particular habitat.

This occurs when one organism consumes another organism. Definition of food webs- Food chains are not strictly linear they have branches type link one food chain with another there may be several interlinked food chains in a community and one animal may be a link in more than one food chains the process of interlink a network of food chain in a community is called food webs food webs includes all the feeding relationships in ecosystem. The feeding level is known as the trophic level.

For example if you had a hamburger for lunch you might be part of a food chain. Producers who make their own food using photosynthesis or chemosynthesis make up the bottom of the trophic pyramid. That is they can form one of the links in a food chain.

In scientific terms a food chain is a chronological pathway or an order that shows the flow of energy from one organism to the other. The producers are represented primarily by the green plants and to a lesser extent by the photosynthetic bacteria. A community of animals plants and microorganisms together with the habitat where they live.

The arrows used to link each organism to the next represent the direction of energy flow. The dead organic substances are decomposed by microorganisms. The organisms that feed on dead organic matter or detritus are known as detritivores or decomposers.
