Here's why:

* Climate is the primary driver of biome distribution: Climate, specifically temperature and precipitation patterns, strongly influence the types of plants and animals that can survive in an area. This in turn shapes the overall structure and characteristics of a biome.

* Other factors play a role: While climate is crucial, other factors like soil type, elevation, and geographic location can also influence biome characteristics. For example, a mountain range can create microclimates and different biomes within a relatively small area.

Therefore, it's more accurate to say that climate is the dominant factor in determining biome distribution, but other factors also contribute.
