Detailed explanation-1: -Mosses decrease the impact of pouring rain and prevent soil erosion by forming dense mats on the soil. Mosses develop a mat or carpet-like structure when they grow in dense strands. As a result, they retain a large portion of the falling water, reducing run-off.

Detailed explanation-2: -Solution : mosses form a protective covering over the crumbling soil of cliffs and prevent the ruching rainwater from cutting deeply into the soil these grow in dense mats so firmly interwined around the soil particles that there can be little erosion, even on a steep hill side.

Detailed explanation-3: -Mosses along with lichens are the first organisms to colonise rocks and hence, are of great ecological importance. Since mosses form dense mats on the soil, they reduce the impact of falling rain and prevent soil erosion.

Detailed explanation-4: -In general, mosses play an integral role in northern ecosystem food webs, because they are eaten by some animals (Prins, 1982), regulate key habitat conditions such as soil climate, and serve as important habitat for soil organisms that interact to form the detrital food web (Lindo & Gonzalez, 2010).

Detailed explanation-5: -Mosses form a protective covering over the crumbling soil of cliffs and prevent the rushing rainwater from cutting deeply into the soil. These grow in dense mats so firmly intertwined around the soil particles that there can be little erosion, even on a steep hillside.
