उत्तर
moss
Explanation:
Lichens are considered to be pioneer inhabitants of a rocky surface. They produce acids like carbonic acids that corrode the rock to form a thin layer of soil. Lichens are succeeded by mosses, which later grow on such surfaces. Rhizoids of mosses penetrate deeper into the rocks and cause the rocks to break up further.
