Readers are introduced to the five basic biomes: tundra, grassland, forest, desert, and water.  A mammal example for each biome is mentioned along with the characteristics needed to survive.  Included is a separate question to encourage inquiry-style thinking about biomes and the animals to have a home there.  Text is in large font.  Illustrations are simple, yet provide adequate information.  A short matching quiz is found in the back along with a small glossary.  Good introduction to biomes for young readers.
