2. Food Webs Food webs show what living organisms are eaten by other living organisms. Food webs are often thought of as a cycle. In a food web, there are primary producers, different levels of consumers, and decomposers.

4. Aquatic Food Web Plants become food for many plant-eating animals. These animals are known as herbivores. Since these animals also are the first ones to eat the producers, they are known as the primary consumers. Some examples of herbivores are mayfly nymphs, small crustaceans, zooplankton, and some kinds of beetles.

Since these animals are eating the primary consumers, they are known as the secondary consumers. Some examples of secondary consumers are minnows, crayfish, and dragonfly nymphs.

6. Aquatic Food Web The secondary consumers are then eaten by bigger animals. These animals are known as tertiary consumers, since they are the third consumers on the food web. Some examples of tertiary consumers are larger fish such as bass, crappies, and perch.
