Detailed explanation-1: -Pioneer species are species which colonize previously uncolonized land, usually leading to ecological succession. They are the first organisms to start the chain of events leading to a livable biosphere or ecosystem. Why is a lichen most likely to be a pioneer species? secondary succession most likely occur?
Detailed explanation-2: -The first organisms appearing in the regions of primary succession are pioneer species (usually lichens or mosses). They are the first species present. They must be strong and hardy.
Detailed explanation-3: -A pioneer species is a species that colonizes an uninhabited area and that starts an ecological cycle in which many other species become established. Over time, a pioneer species will make the new area habitable for other species.
