Detailed explanation-1: -Primary succession occurs in an environment that is vegetation-free, and usually lacks topsoil. Secondary succession develops in areas where, somehow, all living organisms lost, that existed.
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: -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-4: -Primary succession is the process of removing all vegetation from an area. Secondary succession can occur in areas with initial vegetation.
Detailed explanation-5: -Primary succession begins with soil formation. The first stage of succession involves pioneer species. In primary succession, pioneer plants are those that can grow without soil, such as lichens.
