Detailed explanation-1: -Secondary succession: An established community undergoes secondary succession due to a disturbance caused by natural disasters such as wildfires, tornadoes or hurricanes. Human influences such as foresting, farming and development also lead to secondary succession.

Detailed explanation-2: -Secondary succession is the series of changes that take place when there is soil present. For example, after a fire, hurricane, flood, destruction by man, or tornado.

Detailed explanation-3: -Secondary succession follows disasters such as a wildfire, hurricane, or other natural disturbance. Secondary succession can also follow human activities like logging and farming.

Detailed explanation-4: -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.

Detailed explanation-5: -Floodplains represent (like landslides) an intermediate status between primary and secondary succession. At one extreme, floods can completely remove all prior vegetation and organic matter, triggering primary succession on a layer of fresh silt, sand, or gravel.
