What is a community in an ecological context?

A social gathering of people.
A group of interdependent organisms inhabiting the same region and interacting with each other.
A collection of ecosystems.
The global sum of all organisms.

The correct answer is: A group of interdependent organisms inhabiting the same region and interacting with each other.

A community in an ecological context refers to a group of different species or populations living in the same region and interacting with each other. This includes mutualistic, commensal, and competitive relationships among various organisms. Option A is incorrect because it refers to a social gathering of people, which does not encompass all forms of life. Option C is incorrect because a community is not limited to a single ecosystem, but can encompass multiple ecosystems within a region. Option D is incorrect because it refers to all organisms globally, rather than specific interactions within a defined region.
