Answer:
A climax community
Explanation:
A climax community is a relatively stable community in which the component species are in equilibrium with one another.
Ecological succession involves a gradual change of the species composition structure of a community over a period of time.
<em>Depending on the initial state of a community, the species composition keeps changing from pioneer species of a completely new habitat in primary succession through secondary succession and, in the absence of disturbance, to a stable community which is referred to as a climax community.</em>
