Series of changes that occurs after a disturbance in an ecosystem?

Secondary succession is the series of changes that occur after a disturbance (like a forest fire or hurricane) in an ecosystem.

Do not confuse this with primary succession, which is a gradual growth of an ecosystem over a long period of time after a disturbance, such as a volcano that erupted.

The difference is that secondary succession occurs when some vegetation and soil remaining after the disturbance, whereas primary succession occurs when very little or no vegetation or soil is present.
