[Campbell Biology P.676] Which of the following statements accurately describe significant e... | Practice Question
Which of the following statements accurately describe significant ecological, economic, or archaeological contributions of mosses as presented in the text? Select all that apply
A: Certain moss species, like Pleurozium, enhance nitrogen availability in ecosystems by harboring nitrogen-fixing cyanobacteria.
B: Sphagnum moss contributes to the formation of peat, a valuable fuel source, due to its rapid decomposition in peatlands.
C: Mosses, including Sphagnum, are capable of preserving organic matter and even human bodies for thousands of years under specific conditions.
D: Moss cell walls contain phenolic compounds that protect them from damaging levels of UV radiation.
E: Polytrichum moss significantly reduces nitrogen loss from soils through leaching.
Explanation
Option B is incorrect because Sphagnum moss does not decay readily; its resistance to decay is a key factor in peat formation, enabled by phenolic compounds and the unique low temperature, low pH, and low oxygen conditions of peatlands. Options A, C, D, and E are all directly supported by the text.
