Secondary succession occurs after a disturbance in an area in which the soil has remained intact.

Detailed explanation-1: -Primary succession occurs in an environment without previous life, or a barren habitat. Secondary succession occurs in an area that had previously been inhabited but experienced a disturbance, such as a wildfire. The newly created volcanic island has no previous life, and is made of rock, devoid of soil.
Detailed explanation-2: -Secondary succession begins after a disturbance, like a fire. Crucially, some soil and nutrients remain present-fire, in fact, may help recycle those nutrients.
Detailed explanation-3: -Secondary succession occurs when the severity of disturbance is insufficient to remove all the existing vegetation and soil from a site. Many different kinds of disturbances, such as fire, flooding, windstorms, and human activities (e.g., logging of forests) can initiate secondary succession.
