A biome /ËbaÉªoÊm/ is a formation of plants and animals that have common characteristics due to similar climates and can be found over a range of continents.iomes are defined by climate regimes and biogeography. A 1978 study on North American grasslands found a positive logistic correlation between evapotranspiration in mm/yr and above-ground net primary production in g/m 2 /yr.
Earth is the largest ecosystem, divided into biomes, large areas with similar climate and vegetation. A biome is a large ecosystem, extending over a wide geographic region, characterized by certain dominant life-forms â most notably, trees or the lack thereof.n ecosystem is a community of organisms that interact with each other and with the abiotic (chemical and physical) factors in their particular environment. A biome is the largest well-defined ecosystem. Biomes include vast grasslands, continent-wide deserts, and sweeps of arctic tundra.
