Detailed explanation-1: -Secondary succession is typically slower than primary succession. Secondary succession only occurs in mountains, primary succession only occurs in wetlands. Secondary succession is the gradual change in plant species, while primary succession is the gradual change in animal species.

Detailed explanation-2: -In primary succession, newly exposed or newly formed rock is colonized by living things for the first time. In secondary succession, an area that was previously occupied by living things is disturbed, then re-colonized following the disturbance.

Detailed explanation-3: -Primary succession is a slower process than secondary succession.

Detailed explanation-4: -Fewer intermediate communities are formed during secondary succession. No previous community is present in the environment prior to primary succession. Previous communities are present in the environment prior to secondary succession. Primary succession takes a longer time to complete.

Detailed explanation-5: -What is the difference between primary and secondary succession? Primary succession is a process by which a community arises in a virtually lifeless area with no soil. Secondary succession follows a disturbance that destroys a community without destroying the soil.
