Primary succession requires the presence of bare rock or soil, as well as pioneer species that can colonize and begin the process of ecological succession. These pioneer species often include lichens and mosses that can survive in harsh conditions and begin breaking down the rock or soil to create a suitable environment for other organisms.
Primary Succession
A good example of primary succession takes place after a volcano has a secondary succession is a process started by an event.
Things in nature are not black and white, and there are intermediate stages so this makes this question somewhat difficult.Succession that begins in new habitats, uninfluenced by preexisting communities is called primary succession, whereas succession that follows disruption of a preexisting community is called secondary succession.Primary succession: the development of plant and animal life in an area without topsoil; the development of biotic communities in a previously uninhabited and barren habitat with little or no soil.Pioneer succession doesn't exist as a succession term, but pioneer species do.The definition of primary succession fits as the answer to your question.
Secondary succession, where plant and animal life recolonize an area after a disturbance has disrupted an existing ecosystem.
A tornado results in secondary succession. The plants on the surface are destroyed, but buried seeds generally stay in place and the soil remains mostly intact.

primary succession
Primary succession is when living things colonize an area where there were no living things to begin with. For example, after a glacier moves away. Secondary succession is the regeneration of a place that did have colonization. For example, after a forest is cut down.
Secondary succession, where plant and animal life recolonize an area after a disturbance has disrupted an existing ecosystem.
Primary succession, as the area is initially devoid of soil and organisms. Over time, pioneer species like lichens and mosses colonize the barren landscape, eventually leading to the development of a more complex ecosystem.
A tornado results in secondary succession. The plants on the surface are destroyed, but buried seeds generally stay in place and the soil remains mostly intact.
Primary succession
Primary succession
Primary succession and secondary succession differ in several key factors. Primary succession occurs in areas where no soil is present, such as on bare rock or sand, while secondary succession occurs in areas where soil is already present. Primary succession takes much longer to establish a stable ecosystem, as it involves the formation of soil and the colonization of pioneer species. In contrast, secondary succession occurs more rapidly, as it involves the reestablishment of an ecosystem following a disturbance that has left the soil intact.
