Which of the following is true of sphagnum moss in a bog environment?

Sphagnum moss plays a significant role in bog ecosystems, particularly due to its ability to slow the decomposition rate of organic matter. The unique structure of sphagnum moss retains water and creates an anaerobic environment, which limits the activity of decomposers such as bacteria and fungi. In bogs, this leads to the accumulation of peat, a key feature of these ecosystems. The slow decomposition also means that nutrients are not readily recycled back into the environment, creating an ecosystem that is relatively low in nutrients. This characteristic is essential for maintaining the unique biodiversity of bogs, which includes various specialized plant and animal species adapted to these conditions.
