Answer :

The main factor that separates biomes is climate. Climate refers to the long-term patterns of temperature, precipitation, humidity, and other atmospheric conditions in a specific area. These climatic factors greatly influence the types of vegetation, animals, and ecosystems that can thrive in a particular biome.

Different biomes have distinct climate characteristics that determine their overall appearance and biodiversity. For example:

1. Tropical rainforests have high temperatures and heavy rainfall year-round, supporting a diverse range of plant and animal species.

2. Deserts have low precipitation and high temperatures, leading to arid conditions and specialized desert-adapted organisms.

3. Tundra biomes are characterized by extremely cold temperatures and low precipitation, resulting in a unique landscape dominated by mosses, lichens, and cold-adapted animals.

Climate plays a crucial role in shaping the features of each biome, making it the primary factor that separates them from one another.
