A place is categorized as a biome based on the species that live in those areas.
Scientists can define a biome by defining the temperature range, soil type, amount of light, and water that are peculiar to a location and create niches for particular species.
Aquatic, grassland, forest, desert, and tundra are the five basic types of biomes; however, several of these biomes can be further subdivided into more specialized groups, such as freshwater, etc.
Aquatic biome: Any portion of the Earth that is covered with water is considered part of the aquatic biome.
Forest biome: Plants, trees, animals, insects, and microscopic organisms make up the forest biome, which is the largest.
Desert biome: The fact that the desert biome has virtually little vegetation is its most defining feature.
Tundra biome: Tundra biomes are the world's coldest environments.
Grassland biome: Rolling slopes of varied grasses make up the grassland biome.
