Scientists divide the world into large natural areas called biomes. Desert and rainforest biomes are two that you’ve probably heard of. Each biome is known for certain kinds of plants and animals. But what’s really at the heart of a biome is its climate. How hot or cold is it? How much rain and snow fall every year?
Climate is critical because it determines the types of plants and animals—the ecosystem—that can survive in a biome. Polar bears can’t live in the Sahara Desert. Rain forest trees won’t grow in grasslands or the arctic tundra.
