Answer 1

Ans:- a) a)Food chains are oversimplified and suggest that a consumer eats only a single food item.

Is correct reason why food web is prefered over food chain.

A food web consists of many food chains. A food chain only follows just one path as animals find food. eg: A hawk eats a snake, which has eaten a frog, which has eaten a grasshopper, which has eaten grass. A food web shows the many different paths plants and animals are connected
