Succession refers to the gradual process of change in the species structure of an ecological community over time. It's the process of how a barren environment develops into a complex ecosystem. There are two main types:
* Primary succession: Starts with a completely barren environment, like bare rock or newly formed volcanic islands, where no soil exists.
* Secondary succession: Happens when a disturbance, like fire or logging, disrupts an existing ecosystem but leaves the soil intact.
