Ecological succession

Definition

Ecological succession refers to the gradual process of change in species composition and community structure in an ecosystem over time. It occurs as one community replaces another due to natural disturbances or human activities.

Analogy

Imagine ecological succession as a relay race where different teams (communities) take turns running laps on a track (ecosystem). Each team starts from where the previous team left off until they complete their lap and pass the baton to the next team. Similarly, different communities replace each other in an ecosystem during ecological succession.
