what type of succession is the slowest and occurs when all soil has been removed by a significant event and has to be rebuilt? primary succession tertiary succession eutrophic succession
Answer
Brief Explanations:
Primary succession occurs in areas where no soil exists (e.g., after a volcanic eruption or glacial retreat), and soil has to be formed from scratch, making it the slowest. Tertiary succession is not a recognized type of ecological succession, and eutrophic succession relates to nutrient - rich environments (like in lakes) and not soil - rebuilding after total soil removal.
