Question

explain about food web

Answer 1

All living things need food to give them the energy to grow and move. A food chain shows how each living thing gets its food

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. 
eg: A hawk might also eat a mouse, a squirrel, a frog or some other animal. The snake may eat a beetle, a caterpillar, or some other animal. And so on for all the other animals in the food chain.

A food web is several food chains connected together.
