What are biomes?
Biomes are regions of the world with similar climate (weather, temperature) animals and plants. There are terrestrial biomes (land) and aquatic biomes, both freshwater and marine.
How many biomes are there?
There is really no completely right answer to this question. Some people say there are only 5 major types of biomes: aquatic, desert, forest, grassland, and tundra. Others split biomes further. Forests are separated into rainforest, temperate forest, chaparral, and taiga; grasslands are divided into savanna and temperate grasslands; and the aquatic biome is split into freshwater and marine.
