Explanation:
Detailed explanation-1: -Primary succession starts with bare rock, with lichens and moss. Fire is an example of primary succession.
Detailed explanation-2: -Lichens are considered as pioneer species in primary succession on rocks because they can easily grow on rocks where other plants cannot grow. They produce oxalic acid which induced the weathering of rocks and thus soil is formed.
Detailed explanation-3: -Mosses occupy the newly formed rocks, dunes, and many other areas before the origin of other complex plants or organisms. Mosses appear in the area of primary succession; hence they are called pioneer species.
