The term for a collection of animals living in a specific environment is "biome" or "ecosystem." Biomes are large ecological areas that share similar climate, flora, and fauna, while ecosystems focus on the interactions among living organisms and their physical environment. For example, a forest habitat with trees, birds, insects, and other wildlife can be called a forest ecosystem. Each biome, such as deserts, grasslands, or aquatic environments, has distinct characteristics influencing the types of species that thrive there. Understanding these concepts is crucial in fields such as ecology and environmental science.
