Introduce the idea of food webs. A food chain shows one specific route that energy can take through an ecosystem, like one path you could walk to get from your home to school. A food web is like a spiderweb, it has a lot of connections. It shows how different species in an area can interact with each other to meet their energy needs. Most species don't get their energy by eating just one thing. For example, a coyote may eat many different small mammals, insects, carrion (dead meat), and plants.
