Question

1. which factor primarily distinguishes one biome from another? country to country plant size climate soil type

Explanation:

Biomes are large ecological areas on the Earth's surface. Climate (temperature and precipitation patterns) is the primary factor that determines the types of plants and animals that can live in a particular area. Different climates lead to different vegetation structures (like forests, grasslands, deserts) which are key characteristics of biomes. Country - to - country is a political division and not a biological/ecological determinant. Plant size is a characteristic within a biome but not the primary distinguishing factor. Soil type is influenced by climate and while it plays a role, climate has a more overarching influence on biome characteristics.

Climate
