Answer: (D)

Verified step by step guidance

1. Understand the concept of biomes: Biomes are large ecological areas on Earth characterized by specific climate conditions, vegetation types, and the organisms adapted to those conditions.
2. Clarify why biomes are not determined solely by the types of animals present: While animals are part of biomes, the defining factors are primarily climate (temperature and precipitation) and dominant vegetation, which influence the types of animals that can live there.
3. Explain why all biomes do not have the same types of animal species: Different biomes have unique environmental conditions, leading to distinct communities of plants and animals adapted to those conditions.
4. Discuss why biomes are not restricted to a single continent: Biomes such as deserts, forests, and grasslands can be found across multiple continents, as they are defined by climate and vegetation rather than geographic location.
5. Conclude with the correct definition: Biomes are defined primarily by their climate and dominant vegetation, which shape the ecosystem and influence the types of organisms that inhabit them.
