A habitat is best described as the physical environment where a species lives. This definition encompasses not just the location itself but also all the physical components, like water, soil, and temperature, that contribute to the living conditions for the organisms residing there. Habitats can vary significantly in terms of climate, vegetation, and the types of organisms present, making the emphasis on the physical environment crucial.
