Feeding Relationships

It can be difficult to use food chains, like those you studied in the first lesson of the Energy Transfer
series, to depict complex feeding relationships. One organism can potentially belong to multiple
food chains. Take carrots, for example. Carrots not only support rabbits, but also grasshoppers and raccoons. But rabbits support snakes and owls; grasshoppers support frogs, snakes, and raccoons; which are all eaten by owls. That means that carrots are part of at least four different food chains. Now try an activity based on what we just
discussed. Here’s the food web that we just discussed.
