1.
A biome is the largest division of the biosphere.
Large regions within biomes have similar biotic and abiotic components. The interaction of
these components determine the characteristics of the biome.
Temperature and precipitation are the most influential abiotic factors on biomes.
Organisms have adaptations for survival in the specific environmental conditions of their
biome.
