They make their own food using photosynthesis. Hope this helps:

Mosses and liverworts are a simple type of green land plant. They have existed on the earth for millions of years. They do not have the true roots, stems with xylem and phloem and leaves of more developed plants. They do have a simple form of roots called rhizomes and simple structures like leaves. Mosses are found in moist areas and do not grow vertically too high but can spread out to be a yard long. They are found on forest floors and appear as a sort of living carpet. Mosses make their own food through photosynthesis.

Photosynthesis is the making of food by plants. The essential ingredients in making this food are sunlight, the chlorophyll that is present in green plants, water and carbon dioxide in the air. Photosynthesis is necessary not just for plants to make food for themselves, but for animals, including us eventually.

How does photosynthesis occur?

Water is taken in through the roots of the plant and transported to the leaves by the xylem (tubes that carry water) in the stems.

Carbon dioxide animals breathe out from the air goes into the leaves through the tiny pores called stomata and is spreads to the cells that contain chlorophyll in the inside layer of the leaf.

Sunlight is used to break down the water in the plant into oxygen which the plant gives off and we use to breathe. The hydrogen is then used with the carbon dioxide to create the food for the plants and ultimately food for animals as well.

They decompose existing vegetation (i.e trees, vines, plants) And ingest that
