It is easy for ecology to degenerate into lists of vocabulary words and isolated concepts, leaving students without an appreciation for the complexity of ecological systems. This chapter is designed to help students think about the connections between all of the players in both a familiar and a less-familiar ecosystem. The chapter would work well as a concluding activity for an ecology unit or following lessons on food chains, geological cycles (such as water, carbon, and nitrogen), and habitats. It could also introduce an ecology unit, assuming students have had some exposure to ecological concepts in elementary school.
