Detailed explanation-1: -The pioneer species in secondary succession start with roots or seeds that remain after the disturbance. This type of succession occurs faster than primary succession. Secondary succession follows disasters such as a wildfire, hurricane, or other natural disturbance.

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 often follows a wildfire, hurricane, or other natural disturbance. We think of these events as disasters, but many species are adapted to them. Although forest fires kill some trees, for example, other trees are spared, and fire can stimulate their seeds to germinate.

Detailed explanation-4: -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.
