Biomes (2)

Ecologists have divided the terrestrial communities of the world into general groupings called Biomes, which are areas that can be recognized by the distinctive life forms of their dominant species. In most cases, the key characteristic of a biome is its dominant type of vegetation. It could also be said that a biome is a complex of communities’ characteristic of a regional climatic zone. Each biome has its pattern of rainfall, season, temperature and changes of day length all of which combine to support a certain kind of vegetation.
