Detailed explanation-1: -In primary succession, newly exposed or newly formed rock is colonized by living things for the first time. In secondary succession, an area that was previously occupied by living things is disturbed, then re-colonized following the disturbance.
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: -Answer and Explanation: Because the substrate already exists, secondary succession usually happens faster than primary succession. There is no soil in primary succession thus, it must form. This process takes a more extended period because pioneer species must invade the area, die, and soil formed due to this cycle.
