The term for the natural habitat of an organism is "ecosystem." An ecosystem encompasses all living organisms in a particular area, as well as the non-living components of their environment, such as air, water, and soil. This complex interplay of biotic (living) and abiotic (non-living) factors creates a suitable environment where organisms can thrive. Ecosystems can vary greatly in size and characteristics, ranging from a small pond to a vast forest or desert. Understanding ecosystems is essential for conservation efforts, as it helps us comprehend the relationships between different species and their environments, ensuring biodiversity is preserved.
