Which term describes the process of vegetation development after a disturbance when soil remains?

• A. Climax Community
• B. Secondary Succession
• C. Old-Growth Forest
• D. Invasive Species

Answer: (B)

Secondary succession describes vegetation recovery after a disturbance when soil remains. Because the soil is still there, seeds, root fragments, and surviving organisms quickly recolonize the site, and the plant community moves from early pioneers to grasses and shrubs, then to trees, gradually restoring a forest structure. This recovery occurs faster than primary succession, which starts from bare rock or soil-free conditions. The term that describes the final stable community reached after succession is the climax community, but that identifies the end state—not the process itself. An old-growth forest is a mature example of such a climax, not the recovery process. Invasive species refer to nonnative organisms that can disrupt native recovery, not the standard sequence of vegetation development after disturbance.
