Detailed explanation-1: -Solution. Primary succession starts in the area where no living organisms ever existed. In case of secondary succession, since soil is already present, the succession rate is faster and hence climax is also reached quickly. Hence, primary succession is always slower than secondary succession.
Detailed explanation-2: -Primary succession is a slower process than secondary succession. Because, life has to start from a zero, whereas secondary starts at a place that had already supported life before.
Detailed explanation-3: -Secondary succession occurs faster than primary succession because it already has a physical substrate, such as soil that is capable of sustaining life. Primary succession is the development of an ecosystem from scratch starting with hard rocks.
