A biome is a collection of plants and animals that adapted to live in a particular environment. For example, the trees that you find in a rainforest are adapted to grow as tall as they can so they can reach the sunlight. (The rainforest floors tend to be very dark, so plants have to be grow tall to get the sunlight they need to photosynthesise.)

Examples of biomes

Here is the list of biomes you can find on Earth:

• Rainforests: Rainforests have a warm and wet climate. This means it’s quite hot but it tends to rain often. They tend to have lots of plants growing there. Rainforests can be found in countries near the equator, such as Brazil and New Guinea.
  
• Desert: A desert has a hot and dry climate. There is little to no rain but despite this plants, such as cactus, still grow there. Deserts can be found in areas such as Morocco and Egypt. At night, temperatures can get down to – 40C as once the sun goes down, the heat escapes.
