Verified step by step guidance1
Understand the concept of ecological succession, which is the process of change in the species structure of an ecological community over time.
Differentiate between primary and secondary succession. Primary succession occurs in lifeless areas where there is no soil, while secondary succession occurs in areas where a community has been disturbed but soil remains.
Recognize that secondary succession involves the reestablishment of a biological community in an area where the ecosystem has been disturbed, such as after a fire, flood, or human activity, but the soil remains intact.
Identify the key characteristics of secondary succession, including the presence of soil and the faster recovery process compared to primary succession due to the availability of nutrients and seed banks.
Conclude that the best description of secondary succession is the reestablishment of a damaged ecosystem where soil remains intact, allowing for quicker recovery and regrowth of the community.
