Give scientific reasons for the following statements :
The trophic relationships of organisms occur in form of food webs.

Explanation

In nature, organisms are interlinked for food to form food chain.
Among various ecosystems, each one is having definite food chain. But single organism is never dependent only on one organism for food. So trophic relationships for food can never be explained as straight chain. The individuals involved in food chain of one ecosystem are also linked with food chains of other ecosystems.
So, trophic relations for food do not operate in isolation but interlinked to form complex net called food web.
