Accepted Answer

# Brief Explanations:
1. Primary succession indeed starts in areas with no soil like bare rock.
2. Lichens and mosses are pioneer species in primary succession, not secondary. In secondary succession, plants may regrow from existing seeds, roots etc. in the soil.
3. A climax community is stable and mature with little change over time.
4. Forest fires and floods cause secondary succession as soil is present. Primary succession occurs in areas with no pre - existing soil.
5. Secondary succession is faster as soil is already there which contains seeds, roots and nutrients.
For multiple - choice:
1. Primary succession is the development of a community in an area with no soil.
2. Lichens are pioneer species in primary succession.
3. Secondary succession follows events like forest fires where soil is intact.
