WHICH IS NOT A NATURAL ECOSYSTEM IN POND AND SUGARCANE FIELD?

A sugarcane field is not a natural ecosystem; it is an agricultural ecosystem created and managed by humans for the purpose of crop production. In contrast, a pond is a natural ecosystem that supports a variety of organisms, including plants, animals, and microorganisms, interacting in a balanced environment. The key difference lies in the human involvement and management in sugarcane cultivation compared to the self-sustaining nature of a natural pond ecosystem.
