What is a biome?

A biome is defined as a large geographic biotic unit characterized by distinct climate, flora, and fauna. Biomes encompass various ecosystems and are classified based on factors such as temperature, precipitation, and the types of plants and animals that are able to thrive in those conditions. Examples include the tundra, rainforest, desert, and grassland. This definition captures the vast nature and complexity of biomes, making them more than just simple ecosystems or temporary habitats.

The focus on the broad geographic scale, along with the typical climate and ecological characteristics, sets biomes apart in the study of ecology, ensuring that they represent significant and stable ecosystems rather than smaller or more transient environments.
