内容简介：
Through Dwight Kuhn's beautiful, crisp photography and Elaine Pascoe's concise, child-friendly words, PowerKids Press's new series on classification provides a simple introduction to many important life science themes. Kids are introduced to the five kingdoms of life, living and nonliving things, and the concept of sorting living things into groups to better understand the diversity of life. Each book includes a diagram that sorts a kingdom into smaller groups, and photo galleries that further illustrate the features and functions of living things.
