Which of the following is responsible for peat formation?
Correct answer: D. Sphagnum
- A. Marchantia
- B. Riccia
- C. Funaria
- D. Sphagnum
Explanation
(d) : Among the bryophytes Sphagnum accounts by far the most important place economically. It is popularly called bog moss or peat moss. It is perennial and its growth continues year after year. Older portions undergo death but do not decompose due to secretion of acid that accounts for the antibacterial and antifungal actions. The increasing mass of dead remains accumulate year after year and form a compact dark coloured mass rich in carbon which is called peat. Peat is used as fuels. Paraffin, acetic acid, peat tar and ammonia are formed as byproducts of peat obtained for industrial uses
