Detailed explanation-1: -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: -Because these habitats already have soil, secondary succession usually begins with small plants. Climax community can be reached more quickly in secondary succession due to established soil and presence of pioneer species.

Detailed explanation-3: -These conditions favor the development of communities much faster as a result the climax stage is reached much faster in a secondary succession when compared to primary succession.

Detailed explanation-4: -Eventually, enough soil forms and enough nutrients become available such that a climax community, like a forest, is formed. If the site is disturbed after this point, secondary succession occurs. Secondary succession happens when a climax community or intermediate community is impacted by a disturbance.

Detailed explanation-5: -Secondary succession occurs when the primary ecosystem gets destroyed. For eg., a climax community gets destroyed by fire. It gets recolonized after the destruction. This is known as secondary ecological succession.
