What is one key factor that influences a biome's climate?

One key factor that influences a biome's climate is precipitation patterns. Precipitation plays a critical role in determining the type of vegetation that can thrive in a given area, which in turn influences the overall ecosystem characteristics. Different biomes, such as deserts, rainforests, and tundras, are primarily classified based on their average annual rainfall and the seasonal distribution of this precipitation.

For example, tropical rainforests receive high amounts of rainfall throughout the year, which supports a diverse array of plant and animal life. Conversely, deserts receive very little precipitation, limiting plant growth and leading to a different set of organisms that are adapted to arid conditions. Thus, understanding precipitation patterns is essential for comprehending the climate and environmental dynamics of various biomes.
