All animals must eat to survive. Some eat plants. Some eat animals. And others eat both plants and animals. A food chain shows the relationship of each animal to the others.
At the bottom of a food chain are the plant eaters. They are often prey animals. They are usually small animals like squirrels and rabbits. Sometimes they are bigger animals like deer. Animals higher on the food chain eat these animals. They might be owls, snakes, and raccoons. Then, bigger animals like bears and wolves eat these animals. Finally, we reach the top of the food chain. The most dangerous animal of all is here: man.
