Detailed explanation-1: -An ecological community in which populations of plants or animals remain stable and exist in balance with each other and their environment. A climax community is the final stage of succession, remaining relatively unchanged until destroyed by an event such as fire or human interference.

Detailed explanation-2: -Answer and Explanation: A community that has reached a stable stage is called a climax community in ecological succession. Climax communities have reached their peak and have a wide variety of plants and animals.

Detailed explanation-3: -(d) Climax community. Hint: During succession over the rocks, the lichen gets replaced by forests. Similarly, in water bodies also the phytoplankton gets replaced by the forest. So, the ultimate community is the most stable community.

Detailed explanation-4: -A climax community is the “endpoint” of succession within the context of a particular climate and geography. In the midwestern U.S., for example, such a community might be a hardwood forest with oaks and hickories as the dominant tree species.

Detailed explanation-5: -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.
