Question

what is the main difference between primary and secondary succession? secondary succession is caused by human activity, while primary succession is caused by natural disasters. secondary succession is always a much slower process than primary succession. primary succession occurs in areas without soil, while secondary succession occurs in areas where soil is already present. primary succession involves animals, while secondary succession only involves plants.

Explanation:

Primary succession occurs in areas without soil (e.g., newly formed volcanic islands). Secondary succession occurs in areas where soil is already present (e.g., after a forest fire in an area that previously had soil).

Answer:

Primary succession occurs in areas without soil, while secondary succession occurs in areas where soil is already present.
