Most species of moss do not require direct sunlight to survive, but they do need some light to carry out photosynthesis, which is the process by which plants and other organisms convert light energy into chemical energy to fuel their growth and metabolism.
Mosses can grow in a range of light conditions, from full sun to deep shade, but they tend to grow best in partially shaded areas with indirect light. This is because too much direct sunlight can cause moss to dry out and become stressed, while too little light can limit its growth and reproductive success.
In summary, while moss does not necessarily require direct sunlight, it does need some amount of light to thrive and carry out essential life processes.
