An area previously supporting life is made barren, the subsequent recolonization is called _.
Correct answer: D. Secondary succession
- A. Climax community
- B. Pioneer succession
- C. Primary succession
- D. Secondary succession
Explanation
Secondary succession occurs when the primary ecosystem gets destroyed. For example, a climax community gets destroyed by fire. It gets recolonized after the destruction. A climax community is the final stage of succession, remaining relatively unchanged until destroyed by an event such as fire or human interference. Primary succession is an ecological succession that begins in essentially lifeless areas, such as regions in which there is no soil or where the soil is incapable of sustaining life The pioneer species are hardy species that are the first to colonize barren environments or previously biodiverse steady-state ecosystems that have been disrupted, such as by fire. Therefore, the correct answer is secondary succession.
