Detailed explanation-1: -Secondary succession begins in areas where natural biotic communities have been destroyed, such as in abandoned farmlands, burned or cut forests, lands that have been flooded. Since some soil or sediment is present, secondary succession is faster than primary succession.
Detailed explanation-2: -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.
Detailed explanation-3: -Secondary succession takes nearly 50-200 years to finish. Primary succession takes longer durations (nearly 1000 years) than secondary succession. Some examples of the remnants that lead to secondary succession are: Some plants and animals from the previously existing animal-plant community.
Detailed explanation-4: -Secondary succession is faster than the primary succession as the growth media or the soil is already present which allows growth of the plants. The other factors such as the presence of few species also contribute towards the faster rate of growth in the secondary succession.
