Assign students to cooperative groups and ask each group to select a different habitat. Have each group create a new organism that would be adapted well to that habitat. Have them address how it would make its living getting food, its shelter, how it would escape from predators, the environment it would live in, and what things they would want to learn about it if they were scientists trying to study it further. Have students create a diorama with the necessary habitat elements for their imaginary organisms to survive. Each organism has a niche as part of the food web, and there is an interdependence among organisms.
Human actions impact the food web.
List each link on a separate strip of paper. Give each student a piece of a chain. Pass one link out to each person in the class. Discuss what would happen if one organism were eliminated. This page was last updated on April 1, 2001.
