Verified by Experts

The correct Answer is:
B
(a) Low temperature and anaerobiosis inhibit decomposition. Decomposition is mainly an aerobic process. (c ) In aquatic ecosystem GFC is the major conduit for energy flow. As against this in a terrestrial ecosystem a much larger fraction of energy flows through the DFC. (d) Dry weight is more accurate.
