Question

What is ecological balance? why do we need to maintain it?

Answer 1

Ecological balance is a term used to describe the equilibrium between living organisms such as human being, plants, and animals as well as their environment. Photosynthesis that takes place in ecosystem contributes to building a good environment that stabilizes the coexistence of all organisms.
All species are important and help keep the ecosystem balanced. Ecological balance is a term describing how ecosystems are organized in a state of stability where species coexist with other species and with their environment.

Answer 2

Answer:

The balance of nature is a theory that proposes that ecological systems are usually in a stable equilibrium or homeostasis, which is to say that a small change will be corrected by some negative feedback that will bring the parameter back to its original "point of balance" with the rest of the system.
