Succession occurs after ecosystems experience some type of disruptive event
Ecological succession is the steady and gradual change in a species of a particular area concerning changes in the environment. When the change in the ecosystem is disruptive, the concept of success comes into action. Ecological succession aims to recreate the balance and evolve.
There are different types of succession which are the primary succession and the secondary succession. In this case, the succession which occurs after the ecosystem experiences some type of disruptive event is the secondary succession.
