Detailed explanation-1: -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-2: -Secondary succession starts when a disturbance (such as wind storms, insect outbreaks, logging, avalanches, bulldozers, or fire) leaves the soil intact. Seeds, spores, and roots usually remain as well. Sites that begin with secondary succession reach the next stage more quickly than during primary succession.

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: -What is Secondary Succession? Secondary succession is an ecosystem that begins where there was a previous ecosystem present. In the case of secondary succession, an event such as a fire, tornado, volcanic eruption, flood, or other type of catastrophic event took place, destroying the existing ecosystem.
