In primary succession, which term refers to the first species to colonize the area?

The first colonizers in primary succession are pioneer species. These organisms are especially hardy and can survive on bare rock or newly formed land with tiny amounts of soil or nutrients. They initiate soil formation by breaking down rock and adding organic matter from their growth and decay, which gradually makes the environment more hospitable for other species. This initial establishment sets the stage for later stages of succession, as more complex plants and animals can take root. Biomass, phase shift, and primary succession describe other ideas (total mass, change in ecosystem state, and the overall process) rather than the identity of the first colonizing organisms.
