The term for the natural habitat of an animal is "ecosystem." An ecosystem encompasses all the living organisms, including plants, animals, and microorganisms, as well as the physical environment, such as air, water, and soil. Each animal's habitat provides the necessary resources for survival, such as food, shelter, and breeding grounds. These habitats can vary significantly across different ecosystems, ranging from forests and grasslands to deserts and oceans. Understanding animal habitats is crucial for conservation efforts and biodiversity preservation.
