biome, the largest geographic biotic unit, a major community of plants and animals with similar life forms and environmental conditions. It includes various communities and is named for the dominant type of vegetation, such as grassland or coniferous forest. Several similar biomes constitute a biome type—for example, the temperate deciduous forest biome type includes the deciduous forest biomes of Asia, Europe, and North America. “Major life zone” is the European phrase for the North American biome concept.
