Detailed explanation-1: -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. Their nutrients, however, are returned to the ground in the form of ash.
Detailed explanation-2: -Secondary Sector Activities Include manufacturing and construction.
Detailed explanation-3: -So the correct answer is ‘Shifting’.
Detailed explanation-4: -Secondary succession starts when a disturbance (such as wind storms, insect outbreaks, logging, avalanches, bulldozers, or fire) leaves the soil intact. Seeds, spores, and roots usually remain as well. Sites that begin with secondary succession reach the next stage more quickly than during primary succession.
