Answer

Brief Explanations:

Primary succession occurs in areas where there was no previous soil or life. The formation of Surtsey, a new volcanic island, starts with bare rock and no pre - existing community, which is a classic case of primary succession. Harvesting wheat, controlled burning, and the effect of elephants are examples of disturbances in existing ecosystems and lead to secondary succession.

Answer:

the formation of Surtsey, a volcanic island off of the southern coast of Iceland
