Ages 6 to 12 years. Earth has over 30 types of biomes, some of which are home to thousands of ecosystems. All of the plants and animals living in these huge natural areas depend on one another for survival. Children will love learning about life in each major biome. Using simple-to-understand text and beautiful images, this book defines the concepts of biome and climate, and covers: the world's biomes including forests, deserts, grasslands, wetlands, oceans, and the chilly arctic tundra; how wildlife have adapted to their biome's particular climate; biomes in danger.
