Answer:
The correct option is D. potentially interacting populations of different kinds of organisms.
Step-by-step explanation:
In biology, a community can be described as the different populations of organisms that live in a certain habitat at a certain period of time.
For example, consider a habitat where there are a different type of trees, different types of plants, different types of animals, different types of decomposers. All these populations of different organisms will make a community. All the organisms in a community interact with one another in some way or another.
