Verified step by step guidance1
Understand the concept of ecological succession, which is the process by which ecosystems change and develop over time.
Identify that primary succession occurs in lifeless areas where there is no soil, such as after a volcanic eruption or glacier retreat, and involves the gradual establishment of a biological community.
Recognize that secondary succession occurs in areas where a disturbance has destroyed a community but left the soil intact, such as after a forest fire or flood.
Note that primary succession starts from bare rock or barren environments, while secondary succession starts from existing soil and remnants of previous biological communities.
Conclude that the main difference is that primary succession begins in areas without previous life, whereas secondary succession occurs in areas where life has existed before.
