Eat and Be Eaten: How an Ecologist Uses Food Webs introduces students to food chains and food webs, two kinds of diagrams that scientists use as models to show what eats what in an ecosystem. Students follow the work of Thara Srinivasan, an ecologist who has made a detailed study of one lake ecosystem. Students learn how she uses the data that she and other scientists have collected to create computer models of food webs, which help her make hypotheses about what might happen to particular species if pollution continues to accumulate in the lake.
