Detailed explanation-1: -Succession is the idea that an ecosystem is replaced by communities of plants and animals until it reaches a stable, balanced end stage. This end stage is called the climax, and the plants, animals, and other organisms that live in this ecosystem are called the climax community.

Detailed explanation-2: -Primary succession takes longer than secondary succession because soil needs to be created. Soil is already present in secondary succession. 5 steps from primary succession to a climax community (after lava cools and forms rock).

Detailed explanation-3: -Ecological succession is a gradual process of change and replacement of the types of species in a community. The process of ecological succession may take hundreds or thousands of years. Each new community that arises often makes it harder for the previous community to survive.

Detailed explanation-4: -So, the ultimate community is the most stable community. Complete answer: The final stable community in an ecological succession is the ‘Climax community’.
