Return to Platte River Prairies

Food Chains / Food Webs

The interrelationship between species in the river, wetland, grassland, and woodland habitats of the Platte River prairie ecosystem is a complex, dynamic food system. By exploring food chains and food webs, you will discover how energy is transferred from one organism to another. All living things are connected. Here is how it works:

Food Chains

Food Chain Sample

A food chain follows one path as animals find food. For example, an owl eats a snake, which has eaten a mouse, which has eaten grass. A food chain consists of producers (green plants), consumers (animals), and decomposers (microorganisms).

Food Web: Transfer of Energy

Food Webs

A food web consists of many food chains that interconnect and form a complex web-like pattern. A food web is made up of producers and many different levels of consumers.
