Why is it mostly climate that determines the biome of an area?

Climate primarily determines the biome of an area because it influences temperature, precipitation, and seasonal variations, which are critical factors for plant and animal life. Different biomes, such as deserts, forests, and grasslands, are characterized by specific climatic conditions that dictate the types of vegetation that can thrive and the species that can inhabit those areas. Additionally, climate affects soil composition and water availability, further shaping the ecosystem's structure and biodiversity. Overall, the interplay of these climatic elements creates distinct environmental conditions that define each biome.
