Explanation:

To determine how scientists recognize a climax community, we analyze each option:

• Option A: A climax community is stable, so population growth wouldn't be continual. Eliminate A.
• Option B: Climax communities don't rely on resource depletion for recognition. Eliminate B.
• Option C: The environment can still have minor impacts, but the community is stable overall. This is not the key recognition factor. Eliminate C.
• Option D: A climax community is reached when ecological succession is complete and the community is in a stable state, with little to no further change in species composition. This matches the definition.

Answer:

D. Succession is completed, and the community is stable.
