Explanation:
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: -Primary succession is much slower than secondary succession because it begins where there is no soil. It can take several hundred to several thousand years to produce fertile soil naturally. The first pioneer species to colonize the bare rock will probably be bacteria and lichens, which can live without the soil.
