Ages 4-8.    In this science nonfiction picture book, one tree supports an ecosystem of life-insects, mammals, and even humans. A tree is more than just a plant, but a whole ecosystem hiding in plain sight, on street corners and in backyards everywhere. Discover how one tree provides shelter, food, and clean air to a host of animals and insects. Robins build their nest in the branches and bees gather nectar from flowers. The tree keeps its neighborhood clean, healthy, and safe. Leaves clean the air and roots keep the dirt from washing away. The tree's residents are safe through thunderstorms and changing seasons.   40 pages  hc
