Detailed explanation-1: -In secondary succession, a previously occupied area is re-colonized following a disturbance that kills much or all of its community. A classic example of secondary succession occurs in oak and hickory forests cleared by wildfire. Wildfires will burn most vegetation and kill animals unable to flee the area.

Detailed explanation-2: -Secondary succession occurs when the severity of disturbance is insufficient to remove all the existing vegetation and soil from a site. Many different kinds of disturbances, such as fire, flooding, windstorms, and human activities (e.g., logging of forests) can initiate secondary succession.

Detailed explanation-3: -Secondary Succession Stages An area of growth. A disturbance such as fire begins. The fire destroyed the vegetation. The fire leaves behind empty but does not destroy the soil.

Detailed explanation-4: -Explanation: Primary succession occurs in an environment without previous life, or a barren habitat. Secondary succession occurs in an area that had previously been inhabited but experienced a disturbance, such as a wildfire. In this scenario, there still would be soil.

Detailed explanation-5: -Secondary succession occurs opposite to the process of primary succession. It starts after the processes like forest fire, hurricane, etc which reduces the established ecosystem.
