Detailed explanation-1: -Therefore an ecosystem having a climax community experiences the least change in species number over time, hence option d is correct.

Detailed explanation-2: -So, the ultimate community is the most stable community. Complete answer: The final stable community in an ecological succession is the ‘Climax community’.

Detailed explanation-3: -Answer and Explanation: Climax communities are stable because they are very diverse. The diversity of climax communities means that each ecological niche is likely to be occupied by multiple organisms.

Detailed explanation-4: -A climax community can be changed under extreme conditions such as a forest fire or a tidal wave.

Detailed explanation-5: -Soil is already in place, so pioneer species include small plants such as grasses. Most ecosystems are disturbed too often to attain a final, stable climax community.
