Detailed explanation-1: -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. Ecological succession is a fundamental concept in ecology.

Detailed explanation-2: -Succession is a series of progressive changes in the composition of an ecological community over time. In primary succession, newly exposed or newly formed rock is colonized by living things for the first time.

Detailed explanation-3: -Succession: Gradual change in species occupying an area. Due to changes in 1 or more abiotic or biotic factors favoring some species over another. Primary Succession: Gradual establishment of an ecosystem where one did not exist before (Ex: on bare rock).

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 the order of colonization of species in an ecosystem from a barren or destroyed area of land. Mosses and lichens are the first species that inhabit an area. They make the area suitable for the growth of larger species such as grasses, shrubs and finally trees.
