Food webs are basic concepts in biology and ecology, where students learn the concept of energy flow in an ecosystem by  viewing models of food webs.   This labeling worksheet asks students to identify the primary, secondary, and tertiary consumers in a forest ecosystem.

 Students then identify which animals represent carnivores, herbivores and omnivores.  As a final task, students must create their own food web that models an aquatic ecosystem.
