The term REGION OF LIFE can be defined as a BIOME, which is an area of land or water that has distinct plant and animal life. A biome is determined by its climate, soil, and other factors such as elevation and latitude. Biomes are divided into two categories: terrestrial and aquatic. Terrestrial biomes include deserts, grasslands, forests, and tundra, while aquatic biomes include freshwater and marine ecosystems. Each biome has its own unique characteristics and species of plants and animals that have adapted to the environment.
