ONLiNE UPSC · Accepted Answer

Statement 1 is correct: Primary succession occurs in areas where life did not previously exist, such as bare rocks, lava flows, or newly formed sand dunes.

Statement 2 is not correct: Primary succession is slower than secondary succession because it starts from bare, lifeless environments and requires the formation of soil before plants can establish. Secondary succession is faster since it occurs where soil and some life already exist.

Statement 3 is correct: Secondary succession occurs in areas where an existing community has been partially or completely destroyed by disturbances like fires, floods, or human activities, but where soil remains, allowing life to regenerate.
