Detailed explanation-1: -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-2: -The final stage of succession is called the climax community. The stage leading to the climax community is called successional stages or seres.
Detailed explanation-3: -A climax community (Figure below) is the end result of ecological succession. The climax community is a stable balance of all organisms in an ecosystem, and will remain stable unless a disaster strikes. After the disaster, succession will start all over again.
Detailed explanation-4: -Steady state – The final phase is the mature forest. Early successional dominants have died. The majority of the upper canopy are those species able to reproduce with limited amounts of light or that depend on a large disturbance for re-establishment of the dominant species.
