Answer:
..
Pioneer species or lichenExplanation:An ecological succession is a change that occurs within the region related to the abiotic factors which can bring changes in the biotic factors of the region with the course of time until the ecosystem attains stability.The ecological succession over a barren land or a rocky terrain begins with the pioneer species of lichen.The lichen will occupy the land and will secrete the enzymes which will cause the withering of the compact rocks.Thus the available soil will be useful for the growth of new plants.
