Answer

Brief Explanations:

Primary succession occurs in an area where no soil or organisms previously existed. 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 occur in areas with pre - existing soil and communities, which are related to secondary succession.

Answer:

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