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 happens when a climax community or intermediate community is impacted by a disturbance. This restarts the cycle of succession, but not back to the beginning-soil and nutrients are still present.
Detailed explanation-3: -What is secondary succession? Secondary succession occurs in areas where a biological community has already existed but some or all of that community has been removed by small-scale disturbances that did not eliminate all life and nutrients from the environment.
Detailed explanation-4: -Secondary succession can only occur as a transition from primary succession. A recent study has shown an increase in the number of predators in an ecosystem.
Detailed explanation-5: -How does an ecosystem transition from primary succession to secondary succession? During primary succession, pioneer species live off of rocks present in the ecosystem. As time passes, the pioneer species break down the rocks. As the pioneer species decompose, they are mixed in with the broken rock to form soil.
