BiOoomes

The world's biomes
Biomes are defined as "the world's major communities, classified according to the predominant vegetation and characterized by adaptations of organisms to that particular environment". The importance of biomes cannot be overestimated. Biomes have changed and moved many times during the history of life on Earth. More recently, human activities have drastically altered these communities. Thus, conservation and preservation of biomes should be a major concern to all. Here we group biomes into six major types:
Freshwater
Marine
Desert
Forest
Grassland
Tundra
