Neither primary nor secondary succession occurs where no life exists; rather, they both occur in already established ecosystems that have been disturbed. Both primary and secondary succession are gradual processes that involve the colonization and establishment of plant and animal species over time. Additionally, both types of succession involve the development of soil, although primary succession typically involves the formation of soil from bare rock, whereas secondary succession occurs on soil that has already been existing in the ecosystem.
