Paratism is the practice of living as a parasite in or on another organism. Mutualism is the way two organisms of different species exist in which each individual benefits from the activity of the other.
Answer:
Lichens that colonize bare rock secrete acids that break down the rock and start the soil-production process. Also, as lichens die, they provide some organic matter that also contributes to soil. Mosses can then colonize the thin soil; as mosses die, the soil thickens more allowing other hardy species to colonize
Explanation:

The relationship can be obligatory (where the organisms cannot live independent of each other) or can be facultative (where they can also live independent of each other). In lichen, this relationship is facultative.
