How is a biome defined?

A biome is defined as a large geographical community characterized by specific climatic conditions and distinctive flora and fauna. This definition encompasses the ecosystems found in that area, making it a broader classification than a localized region. Biomes are typically distinguished by their climate, such as temperature and precipitation patterns, which in turn shape the types of plants and animals that can thrive there. Examples of biomes include deserts, forests, grasslands, and tundras.

Understanding a biome involves recognizing how the environment influences the types of organisms that inhabit it, which aligns with the concept of ecological communities that interact with each other and their physical surroundings across a large area. This perspective positions biomes as extensive and consistent patterns of life, distinguishing them from smaller or temporary ecological constructs.
