Ecological succession is a gradual process of species replacement in ecosystems, with primary succession occurring on barren land following a disturbance like a forest fire, replacing species with minimal disruption.
Ecological succession refers to the process by which ecosystems undergo changes in species composition over time. In a pioneer community, such as after a forest fire, primary succession occurs when new ecosystems develop on barren land. This type of succession gradually replaces a small number of species at a time, causing minimal disturbance to the community.
