Food Webs

Organisms in a food chain often eat-and get eaten-by more than just one thing. Rabbits don't eat just grass. They also eat clover,leaves,and shrubs.
In the grass isn't eaten just by rabbits aren't eaten just foxes. They re also prey to coyotes and wolves. Foxes eat squirrels, toads,chipmunks, and rabbits.
 This connection among food chains forms a food web. Food Webs are overlapping food chains within an ecosystem.

Food chains and food webs occur in the water as well as on land. Even in the water, almost all food chains begin with energy form the Sun. Tiny organisms in the ocean called phytoplankton make their own food from the sun's energy.
