Verified step by step guidance1
Understand the concept of primary succession: It is the process of community development in a previously uninhabited and barren habitat with no soil, such as a newly formed volcanic island or a region left bare by a retreating glacier.
Identify the key characteristics of primary succession: It involves the gradual establishment of a biological community, starting with pioneer species like lichens and mosses that can survive in harsh conditions and contribute to soil formation.
Differentiate primary succession from secondary succession: Secondary succession occurs in areas where a community has been disturbed but soil remains, such as after a forest fire or agricultural activity.
Evaluate the options given in the problem: Eliminate choices that do not align with the definition of primary succession, such as those involving existing soil or rapid colonization.
Select the option that accurately describes primary succession: The gradual establishment of a biological community in an area where no soil previously existed.
