Which of the following statements is correct for secondary succession?

Options

A. It occurs on a forested site
B. It follows primary succession
C. It is similar to primary succession except that it has a relatively fast pace
D. It begins on a bare rock

Answer

To determine the correct statement regarding secondary succession, let's analyze the provided statements step by step.

### Step-by-Step Solution:

1. **Understanding Secondary Succession**:
- Secondary succession is a process that occurs in areas where a community previously existed but has been disturbed or destroyed. This could be due to events like forest fires, floods, or human activities such as deforestation.

2. **Evaluating the Statements**:
- **Statement 1**: "It occurs on a forested site."
- This statement is partially true as secondary succession can occur in forested areas that have been disturbed, but it is not limited to just forested sites. Therefore, it is not entirely correct.

- **Statement 2**: "It follows primary succession."
- This statement is incorrect. Secondary succession does not follow primary succession; rather, it occurs independently in areas where a previous community existed.

- **Statement 3**: "It is similar to primary succession except that it has a relatively fast pace."
- This statement is correct. Secondary succession is indeed similar to primary succession in that both involve the gradual replacement of species over time, but secondary succession occurs more quickly because the soil and some organisms are already present.

- **Statement 4**: "It begins on bare rock."
- This statement is incorrect. Secondary succession does not start on bare rock; that is characteristic of primary succession. Secondary succession begins in areas where soil and some form of life already exist.

3. **Conclusion**:
- The correct statement regarding secondary succession is **Statement 3**: "It is similar to primary succession except that it has a relatively fast pace."
