Question

did you find any example of human inference in those ecosystem

Answer 1

An ecosystem consists of the living and non-living things that interact with one another in a particular location. In the example above, the fish and plants both live in the water, plants provide oxygen for the fish and rocks provide them with shelter, and the fish nibble at the plants and prevent overgrowth. All of the elements of the ecosystem you have created are in harmony. When this type of stability exists in an ecosystem, we call it a balanced ecosystem.
