In which situation will primary succession most likely occur?
Primary succession is most likely to occur in situations where there is no pre-existing soil or organic matter, such as on bare rock or sand dunes, as well as in areas that have been disturbed by natural events such as volcanic eruptions, landslides, or glacial retreat.

Primary succession is likely to occur in situations where the bare rock or barren land is void of any living organisms or soil. It is a process that occurs in areas that have been completely devoid of life, such as after volcanic eruptions, glacial retreat, or the formation of new land surfaces like sand dunes.
To determine which situation is most likely to experience primary succession, we can consider these factors:
1. Volcanic eruptions: After a volcanic eruption, the lava and ash cover vast areas, sterilizing the land and destroying any existing life. This provides an ideal scenario for primary succession.
2. Glacial retreat: As glaciers retreat, they leave behind barren land stripped of vegetation. This exposed land can lead to primary succession, as there are no living organisms or soil to support immediate recolonization.
3. Formation of new land surfaces: When new land surfaces are formed, such as sand dunes or newly exposed rock, there is no pre-existing soil or living organisms present. This creates conditions that promote primary succession.
In summary, primary succession is most likely to occur in situations where there is a lack of living organisms and soil, such as after volcanic eruptions, glacial retreat, or the formation of new land surfaces.
