Detailed explanation-1: -Succession refers to a directional, predictable change in community structure over time (Grime 1979, Huston & Smith 1987). This change is due to shifts in the presence and relative abundance of different species as time passes over years to centuries.

Detailed explanation-2: -Ecological succession is a series of more-or-less predictable changes that occur in a community over time. Ecosystems change over time, especially after disturbances, as some species die out and new species move in. Over the course of succession, the number of different species present typically increases.

Detailed explanation-3: -By Max Witynski. 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.

Detailed explanation-4: -For over a century, ecologists have investigated the nature of these changes in communities, documenting the causes and patterns of change, indentifying mechanisms for change, and developing sets of general principles to explain this change. This change in community composition over time is termed succession.

Detailed explanation-5: -Succession is a scientific term describing the long-term progression of biological communities that occurs in a given area. Ecological succession breaks down into three fundamental phases: primary and secondary succession, and a climax state.
