3. Food Webs

Food Webs

What is a more accurate way to depict the passage of energy in an ecosystem? A food web recognizes that many organisms eat at multiple trophic levels.

A food web includes the relationships between producers, consumers, and decomposers.

Even food webs are interconnected. All organisms depend on two global food webs. The base of one is phytoplankton and the other is land plants. How are these two webs interconnected? Birds or bears that live on land may eat fish, which connects the two food webs.

Humans are an important part of both of these food webs; we are at the top of a food web, since nothing eats us. That means that we are top predators.
