Answer
The correct answer is d. primary succession.
1Step 1: Define the Process
The first step is to identify the process described. Here, the change being referred to is the transition from lifeless rock to a fully established and diverse community of vegetation, a process that occurs over a very long timeframe.
2Step 2: Link Term to Definition
Next, match the correct terminology with the identified process. Using scientific knowledge, it is known that the process of a bare and lifeless ecosystem developing into a complex ecological community is defined as a type of ecological succession.
3Step 3: Choose the Correct Type of Succession
Lastly, make a choice between primary and secondary succession. This particular succession, starting with barren rock, is actually the first establishment of an ecosystem in an area, which leads us to conclude the type of succession is primary.
