Explanation:

An ecological community consists of all the different species (biotic factors) interacting in a particular area. Option A is a single species (population), B is also a single species (population). Option D includes abiotic factors (sand, pH, etc.), which makes it an ecosystem. Option C has multiple species (corals, fish, plant life) in the Great Barrier Reef, fitting the definition of a community.

C. All of the corals, fish, and plant life in the Great Barrier Reef.
