Detailed explanation-1: -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-2: -Unlike primary succession, secondary succession occurs in a place where an ecosystem currently exists. Some examples of primary succession can be a new island formed by the eruption of an undersea volcano. An example of secondary succession is when a natural disturbance has happened and organism and soil still exist.

Detailed explanation-3: -Secondary succession-Succession where natural communities develop in an area that was earlier occupied by living organisms that were somehow lost. It begins in areas where natural biotic communities have been destroyed such as in abandoned farm lands, deforested lands, lands that have been flooded, etc.

Detailed explanation-4: -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-5: -Secondary succession occurs in an area that had previously been inhabited but experienced a disturbance, such as a lava flow. Secondary succession occurs in environments that have been distrubed, but have some remaining soil and vegetation.
