A biota is a term used for all the living things at a certain time at a certain place. Examples of biota include Cambrian biota and Madagascan biota. Because it includes all the living members of a given environment, the term is used especially in ecology. A similar term is biome, which is used to refer to geographical regions and environments. Tundra, for example, is a biome.
Flora, fauna and other forms of life such as fungi are collectively called biota.
