The correct answer is c ecosystem.
An ecosystem encompasses all the living organisms, including plants and animals, in a specific area along with their physical environment. It includes the interactions among these organisms and how they relate to their surroundings. While a ‘community’ refers specifically to the various populations of different species living in the area, the term ‘ecosystem’ includes both the biotic (living) and abiotic (non-living) components. So, when we consider everything in a location—from the soil and water to the plants and animals—a complete ecosystem is what we are referring to.
