Question

choose the correct answer. 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 eutrophic succession tertiary succession

Explanation:

Primary succession occurs in lifeless areas where soil has been removed (e.g., after a volcanic eruption). It starts from bare rock and takes a long time as soil has to be formed from scratch through processes like weathering and the action of pioneer species (lichens, mosses). Eutrophic succession is related to the aging of water bodies (e.g., a lake becoming more nutrient - rich over time). Tertiary succession is not a commonly recognized major type of ecological succession in the basic ecological concepts.

Answer:

primary succession
