Major Biomes of the World

Updated August 5, 2020 | Infoplease Staff

Have you visited any biomes lately? A biome is a large ecosystem where plants, animals, insects, and people live in a certain type of climate. If you were in northern Alaska, you would be in a frosty biome called the Arctic tundra. If you jumped on a plane and flew to Brazil, you could be in a hot and humid biome called the tropical rainforest. The world contains many other biomes: grasslands, deserts, and mountains, to name a few. The plants and animals living in each are as different as their climates. Which is your favorite?
