What primarily characterizes biomes?

Biomes are primarily characterized by their climate, vegetation, and types of wildlife because these factors create distinct ecological communities that thrive in specific environmental conditions. Each biome has a unique set of temperature and precipitation patterns, which play a crucial role in determining the types of plants that can grow in the area. The vegetation then influences the kinds of animals that can inhabit that biome, as different species rely on specific plant types for food and habitat. For instance, a tropical rainforest biome supports a diverse range of flora and fauna due to its warm temperatures and high rainfall, while a desert biome—characterized by low rainfall and extreme temperatures—supports a completely different set of organisms adapted to those harsh conditions. Recognizing the interplay between climate, vegetation, and wildlife helps us understand the ecological dynamics and biodiversity within each biome.
