Answer: (A)

Verified step by step guidance

1. Understand the concept of ecological succession: It refers to the natural process by which ecosystems change and develop over time, often following a disturbance.
2. Differentiate between primary and secondary succession: Primary succession occurs in areas where no soil exists (e.g., after a volcanic eruption), while secondary succession occurs in areas where the soil remains intact after a disturbance (e.g., after a forest fire).
3. Analyze the scenario in the question: The disturbance destroys the community but leaves the soil intact, which aligns with the definition of secondary succession.
4. Review the other options: 'Primary succession' does not apply because soil is already present. 'Climax community' refers to the final, stable stage of succession, and 'Ecological restoration' involves human intervention to restore ecosystems.
5. Conclude that the correct term describing this process is 'Secondary succession,' as it matches the scenario described in the question.
