Explain the role of mosses and lichens in primary succession?

They begin life in a lifleless habitat.

Explanation:

A primary succession is a phenomenon that leads to the development of flora and fauna in an area that had previously been uninhabited.

Lichens are a combination of fungi and algae that release acids which help in the growth of other organisms like mosses and other tiny organisms.

Lichens and moses act as a catalyst in primary succession. They not only initiate the process but also serve as 'pioneer species'.

As 'pioneer species', they help in transforming the rock into soil, thereby contributing to the vegetation of grass and other plants.

answer:

the water molecules are transferred from the roots to the stem or top parts of the tall tree because of important properties of water which are adhesion, cohesion and capillary action. cohesion is the property of water molecules keeps water molecules in a combined state by sharing of bonds between them at the atomic level. adhesion allows the interaction of water molecules with other substances or substrate. adhesion will cause the attachment of water molecules to the wall of the vessel (xylem) of the plant. capillary action occurs when the adhesive force to the vessel wall is stronger than the cohesive force between water molecules. capillary action mimics the transfer of water from a tube or pipe. in this way water utilizes its property to transfer water from down to top level of the plant.
