Mosses decompose rocks and release nitrogen.

Explanation:

Mosses are very important for the functioning of life as we know it and for the nitrogen cycle in the nitrogen return stage to the soil. In addition to absorbing, like real sponges, large amounts of rainwater, keeping the soil surface moist and forming the peat used as fuel, mosses break down the rocks on which they grow, releasing nitrogen that will return to the soil.

Mosses are primitive plants that do not produce flowers, fruits and seeds and also do not produce vascular tissues. For this reason they are called avascular or non-tracheophyte plants. The absence of conductive tissue is largely responsible for the small size of these vegetables.
