How is a biome defined?

A biome is defined as a large geographical biotic unit characterized by specific climate and ecosystems. This definition encompasses the various types of wildlife and vegetation that thrive in an area due to its climate conditions, such as temperature, precipitation, and seasonality. Each biome, like a desert, rainforest, or tundra, has distinct ecological communities adapted to those specific environmental factors.

The emphasis on "large geographical" indicates that biomes cover extensive areas and are not limited to small regions or single habitats. This broad scope allows for the inclusion of multiple ecosystems and the diversity of organisms within them. Understanding biomes helps us appreciate the complexity and interconnections of life on Earth, as well as the influence of climate on biological communities.
