Question

which type of succession is considered to be the fastest? primary tertiary secondary

Explanation:

Secondary succession occurs in areas where a disturbance has destroyed an existing ecosystem but left the soil intact. Since soil is already present, it has a head - start compared to primary succession (which starts on bare rock with no soil) and tertiary succession (a less common and often misused term, with secondary being the recognized faster one among the given options). So, secondary succession is generally faster as there are already seeds, roots, and other propagules in the soil that can quickly regrow and colonize the area.
