Biomes are geographic regions

Question

Quizplus · Accepted Answer

Biomes are defined by the plant communities that inhabit them, which have evolved similar adaptations to the shared conditions of the region. These adaptations determine the dominant vegetation, which in turn affects the animal communities and their adaptations. Therefore, choice D - whose plant communities have similar adaptations - best describes biomes. Choices A and B are incorrect because while certain species may be more common in a particular biome, there may be variation in the presence of key species among different locations within the biome. Choice C is also incorrect because while temperature range is one important factor influencing biome distribution, it is not the only factor, and there can be biomes with a range of temperatures.
