A. Secondary succession. "Secondary succession is one of the two types of ecological succession of plant life. As opposed to primary succession, secondary succession is a process started by an event (e.g. forest fire, harvesting, hurricane) that reduces an already established ecosystem (e.g. a forest or a wheat field) to a smaller population of species, and as such secondary succession occurs on preexisting soil where as primary succession usually occurs in a place lacking soil."
