Answer 1

Different populations living in a same environment interacting with each other is called a community.

Explanation:

The community is a group of different species and populations of organisms that are living in a particular ecosystem and are interacting with each other for the benefit. The interaction may be symbiotic, or commensal, or ammensal, or parasitic, or normal prey-hunter relationship. This relationships help all the populations remain in their normal population sizes, and to keep the resource availability to maximum, and to keep a stable ecosystem.

This is the reason why Introduction of any exotic species in the community leads to the disruption of food chains and normal activities of the community.
