Detailed explanation-1: -Q. Reaches a climax community quicker because soil is already present when succession begins. Q. Secondary succession occurs where an ecosystem has previously existed.

Detailed explanation-2: -Secondary succession usually occurs faster than primary succession because the substrate is already present. In primary succession, there is no soil and it needs to form. This process takes time, as pioneer species must colonize the area, they must die, and as this happens over and over again, soil forms.

Detailed explanation-3: -Secondary succession is the ecological succession that occurs after the initial succession has been disrupted and some plants and animals still exist. It is usually faster than primary succession as soil is already present, and seeds, roots, and the underground vegetative organs of plants may still survive in the soil.

Detailed explanation-4: -Secondary succession. Secondary succession occurs when the starting point is bare soil that already exists. It is similar to primary succession, however, the pioneer species are often fast-growing plants and often come from pre-existing groups of organisms in the area.

Detailed explanation-5: -Secondary succession is more common and usually occurs faster than primary succession because the substrate is already present. Secondary succession occurs on a surface where an ecosystem has previously existed. This happens after some sort of disturbance.
