Succession is the process by which a community of organisms gradually changes over time in a predictable manner following a disturbance or the colonization of a new habitat. It involves the colonization and establishment of new species in an area and the replacement of those species by others in a specific sequence. Succession can occur in a variety of ecosystems, such as forests, grasslands, and wetlands, and can be influenced by factors such as climate, species interactions, and human activities. Studying succession can help ecologists better understand how ecosystems recover from disturbances and how they change over time.
