Question

Decomposition rate of detritus is fastest if rich in nitrogen

Answer 1

Decomposition is largely an oxygen-requiring process. The rate of decomposition is affected by chemical composition of detritus and climatic factors. Decomposition rate is slower if detritus is rich in lignin. Decomposition rate is quicker if detritus is rich in nitrogen and water-soluble substances like sugars. Warm and moist environment favors decomposition, but low temperature and anaerobiosis inhibit decomposition.

Decomposition: Conversion of complex organic matter into inorganic substances by decomposers is called decomposition.

Detritus: It is the raw material for decomposition. It is composed of dead remains of plants and animals; including faecal matter.
