Biomes are different types of ecosystems that can be identified by their unique features and origins. They can be classified based on factors like climate, vegetation, and geography. In the Southern Hemisphere, a new system is being developed to better understand and categorize these biomes. This system will focus on how climate influences the formation of biomes on a large scale. By studying the relationship between climate and biomes, scientists hope to create a more comprehensive and accurate classification system for the diverse ecosystems found in the Southern Hemisphere.
