Module Summary – DSCR Ecosystems
The Delta Science Content Reader Ecosystems begins by defining what an ecosystem is. Students learn about the living and nonliving parts of an ecosystem and how they interact, with a pond as an example. They explore the diversity of life within ecosystems and how different organisms in an ecosystem meet their own needs and compete for resources. The book concludes by discussing how scientists trace the flow of energy and matter as they move through ecosystems.
