Explanation:
Detailed explanation-1: -Primary Succession Soil starts to form as lichens and the forces of weathering and erosion help break down rocks into smaller pieces and move them to new areas.
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.
