Detailed explanation-1: -Secondary succession occurs after a disturbance such as a forest fire, where there is still some organic matter to allow new plants to grow.
Detailed explanation-2: -Forest → Forest fire → Severe forest fire → Total nudation of forest land → Terrestrial plants → Shrubs → Woodland Stage → Forest Stage The forest fire leaves behind an empty but not destroyed soil (Nudation), over which secondary succession begins.
Detailed explanation-3: -Primary succession begins when no plant life is present on the landscape, such as after a lava flow or glacial retreat. Over centuries, soil forms and deepens and successive communities of plants grow.
Detailed explanation-4: -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.
