Canadian And World Studies (CGC1W) Practice Exam

A biome is best described as what?

A large ecosystem characterized by a distinctive climate and communities of organisms. A single species habitat. A political boundary. A rainfall measurement region.

Correct Answer:

A large ecosystem characterized by a distinctive climate and communities of organisms.

Explanation:

Biomes are large ecological regions defined by their climate and the communities of organisms that thrive there. The climate—patterns of temperature and precipitation—shapes which plants dominate and, in turn, which animals can live there, so a biome represents a broad, recognizable system that includes many ecosystems with similar conditions. It’s bigger than a single species’ habitat, and it isn’t about political boundaries or rainfall measurements alone. The best description is a large ecosystem characterized by a distinctive climate and communities of organisms.
