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 grassland. And the aquatic biome is split into freshwater and marine.
