A biome is defined by its biogeography temperature and precipitation; thus biomes are distinguished from one another by differences in biogeography temperature and precipitation.

Biogeography refers to how species and ecosystems are distributed in space. Thus a biome is distinguished from other biomes not only by temperature and precipitation but also by the evolutionary history of the organisms inhabiting it.
The organisms inhabiting a particular biome are determined in large part due to the temperature and precipitation of the area. The plants and animals found in a specific biome will be adapted to it.

Note: there are definitions of biomes and their classification that differ slightly from one another. Read more about biomes and their classification here and here.
