Food chain definition environmental science. However there are several reasons why a food chain may become disrupted. 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.

Every living thingfrom one-celled algae to giant blue whale sneeds food to survive. An example of food chain is a fly being eaten by a frog and then the frog is eaten by a larger animal. The chain of organisms which involves transfer of energy from one trophic level to next trophic level is called as food chain.
