Final answer:
A biological community consists of the different species within an area and the interactions within and among these species.
Step-by-step explanation:
A biological community consists of the different species within an area and the interactions within and among these species. It is the biotic part of an ecosystem and includes all the populations of all species that live in the ecosystem and their relationships with each other.
For example, in a forest, the community would include populations of trees, flowers, insects, and other organisms that live in the forest.
Community relationships include predation, competition, symbiosis, and parasitism.
