sphagnum moss is a type of moss that typically grows in wet, acidic environments, such as bogs and wetlands. It has a unique ability to retain water, making it an important component of these ecosystems. Sphagnum moss can hold up to 20 times its weight in water, which helps to create a habitat for various plants and animals. This moss plays a crucial role in carbon storage, as it accumulates peat over time. Peat is formed from the slow decomposition of plant material in waterlogged conditions. Because of its ecological significance, sphagnum moss is often studied in relation to climate change and biodiversity.
