Explain how ecosystems are sustained through succession.

Answer:

Succession allows ecosystems to recover from events. Even ecosystems that have no soil, such as those that have been destroyed by volcanic activity, can return to a stable and sustainable state. Primary succession occurs in these ecosystems. Pioneer species are found in areas undergoing primary succession. These pioneer species help reform soil over time. After soil is present, new species can move into an area during secondary succession. After a longer period of time, climax communities can be reached.
