Detailed explanation-1: -Secondary Succession occurs on a pre-existing soil just after primary succession was interrupted or lost due to disruption that reduced the initial inhabitant’s population. Thus, the right answer is option B i.e., Primary succession begins with lichens.
Detailed explanation-2: -Secondary succession happens when a climax community or intermediate community is impacted by a disturbance. This restarts the cycle of succession, but not back to the beginning-soil and nutrients are still present.
Detailed explanation-3: -Some examples of primary succession include the formation of a new ecosystem after a volcano, glacier outbursts, or a nuclear explosion. Some examples of secondary succession include succession after fire, harvesting, logging, or abandonment of land or the renewal after a disease outbreak.
