Delta Science Readers: Food Chains and Webs

In the Delta Science Reader Food Chains and Webs, students read about what an ecosystem is, how living things in an ecosystem get energy, and how ecosystems can change. Students explore the interaction of living things and discuss food chains and webs. The book also presents biographical sketches of key scientists—Charles Darwin and Rachel Carson—and describes the work of an ecologist.
