Detailed explanation-1: -What is the relationship between ecological succession and equilibrium in an ecosystem? Ecological succession helps maintain equilibrium in an ecosystem. Ecological succession prevents ecosystems from ever reaching equilibrium.

Detailed explanation-2: -In some environments, succession reaches a climax, which produces a stable community dominated by a small number of prominent species. This state of equilibrium, called the climax community, is thought to result when the web of biotic interactions becomes so intricate that no other species can be admitted.

Detailed explanation-3: -Equilibrium in ecology refers to a state that occurs such that a small disturbance or change is counter balanced by another change so that the community is restored to its original state. Thus, as a community goes through multiple changes through each stage of succession, it is not in equilibrium.

Detailed explanation-4: -Communities with a stable structure are said to be at equilibrium. Following a disturbance, the community may or may not return to the equilibrium state. Succession describes the sequential appearance and disappearance of species in a community over time.

Detailed explanation-5: -Ecological succession is the process by which the mix of species and habitat in an area changes over time. Gradually, these communities replace one another until a “climax community”-like a mature forest-is reached, or until a disturbance, like a fire, occurs.
