Food chains Book

In this three-book series, readers learn "what goes around comes around" in nature's major cycles. Providing a serious basis for biological study, each title examines how humans disrupt critical cycles and suggests ways in which we can protect those cycles. Straightforward text, large vibrant photos, and clear diagrams encourage readers to investigate. Activities and question boxes stimulate further thought and discussion, and each title includes a glossary, further information, and index.
