What is the difference between food chains and food webs?

Food chins go in one direction, like a chain and food webs go in lots of different directions.

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
