Detailed explanation-1: -Secondary succession occurs after a disturbance such as a forest fire, where there is still some organic matter to allow new plants to grow. Both types of succession take place over long periods of time and result in the communities reaching a state of equilibrium.
Detailed explanation-2: -Ecological succession is the constant replacement of one community by another. It happens after a big change in the ecosystem. Primary succession can take place after lava flow cools and hardens into new land, or a glacier recedes exposing new land.
Detailed explanation-3: -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-4: -Primary succession takes much longer than secondary succession, because it involves.
