Solution ✔ Verified
  • APrimary succession occurs on previously vegetated land, while secondary succession occurs on bare ground.
  • BPrimary succession typically takes much longer than secondary succession to reach a climax community.
  • CSecondary succession is always initiated by human disturbance, while primary succession is natural.
  • DPrimary succession involves the gradual replacement of species, while secondary succession involves abrupt changes.
Explanation

Primary succession begins on newly exposed or formed land where no soil exists (e.g., volcanic rock), making it a very slow process. Secondary succession occurs in areas where a community has been removed but the soil remains intact (e.g., after a fire), so it typically proceeds much faster.
