The sequence described is an example of ________ by stages.

The sequence described is an example of ________ by stages.

• A. Secondary Succession
• B. Primary Succession
• C. Tertiary Succession
• D. Quaternary Succession

Answer: (A)

Succession is the progressive change in plant and animal communities after a disturbance, proceeding through seral stages toward a stable climax. When this change happens with the soil and some remnants still present, it’s secondary succession because recolonization uses existing soil, seeds, and roots. The sequence by stages typically starts with fast-growing grasses and herbs, moves to shrubs, and finally trees, reflecting how a disturbed area regrows quickly due to nutrients in the soil and the seed bank that remain. This contrasts with primary succession, which begins on bare rock or barren land with no soil, and must build soil from scratch, taking longer. Terms like tertiary or quaternary aren’t the standard labels for the main stages in introductory ecology, so the described pattern fits secondary succession.
