Fitting Algae Into the Food Web
This activity will help students understand food chains and food webs in the ocean. After studying the materials provided, students will play a food web game, in which they are given a blank food web and the names of the organisms. Students place the organisms in their correct places on the food web so that the arrows indicate the direction of energy flow. As a follow-up, students decide what would happen if they removed one of the organisms from the food web, consider the role of decomposers, and deal with geographic variation. Students should also be able to understand the importance of and need for primary producers, the interdependence of organisms, the role of bacteria in the food web, and geographic variation in food webs.
