Ants growing fungus gardens? Medicine derived from tree bark? Chocolate made from seeds? Welcome to the tropicaland temperaterain forests. With at least 100 inches of rain annually, more kinds of plants grow here than anyplace else on Earth. Depending on where in the four forest layers they live (forest floor, understory, canopy, emergent layer), plants survive by developing adaptations like large leaves to capture faint sunlight or waxy leaves to protect them from too much moisture. Canopies support most of the wildlife (monkeys, toucans, squirrels, and more), while beetles, jaguars, and eagles live in other layers. People harvest foods like bananas and pineapples here and also find medicinal breakthroughs like quinine. Development is a threat, as people have already cut down more than 50% of rain forests. Dell features tank bromeliads, which become mini-biomes with resident frogs, snails, and crabs that might live their entire lives inside the bromeliad's tank. If you are looking for a way to introduce young readers to biomes, you've found it. Each book in this series defines the biome, talks about native plants, discusses how the plants are used by both animals and humans, explains the dangers to these plants and protections for them, and showcases one plant. Two-page spreads consist of a photo page and a text page. Text is simple, clear, and brief. Twenty-four pages include a table of contents, a glossary, references (including FactHound), and an index. Other titles in the "Life in the World's Biomes" series include Desert Plants, Ocean Plants, and Wetland Plants. 2006, Bridgestone Books/Capstone Press, Ages 7 to 10.
