The text describes several factors that inhibit the decay of Sphagnum moss in peatlands, leading to peat formation and preservation. Which of the following are among these factors? Select all that apply

  • A: The presence of high concentrations of phenolic compounds in Sphagnum cell walls.
  • B: The high temperature prevalent in boggy wetlands.
  • C: The acidic (low pH) conditions of peatlands.
  • D: The low oxygen levels within peatlands.
  • E: The rapid water flow through peatlands, washing away decomposers.

Explanation

The text explicitly states that Sphagnum does not decay readily due to 'phenolic compounds embedded in its cell walls. The low temperature, pH, and oxygen level of peatlands also inhibit decay.' This directly supports options A, C, and D. Options B and E contradict the information provided or are not mentioned.
