/ˈbaɪoʊm / (say 'buyohm)

a major regional ecological community of plants and animals adapted to a particular climate or environment and extending over a large geographical area, as coral reef, tropical rainforest, etc.
{bi(o)- + -ome}
Biomes occupy large areas of the earth's surface and their distribution is a function of geological factors, seasonal insolation changes and global climate patterns. The essential concept of a biome is of a defined community with interaction between vegetation, animal populations and soil. Each biome is identified by its dominant vegetation type (for instance, grassland, monsoon forest or desert) and defined by the associated communities of species adapted to the conditions in which they occur. The particular species within a biome can alter according to local differences such as soil or microclimate. Similarly, a given biome may be composed of different species on different continents.
