The rate of decomposition is faster in the ecosystem due to following factors EXCEPT :

Options

  1. ADetritus rich in sugars
  2. BWarm and moist environment
  3. CPresence of aerobic soil microbes
  4. DDetritus richer in lignin and chitin

Correct answer

D. Detritus richer in lignin and chitin

Step-by-step solution

The rate of decomposition of detritus is controlled by the chemical nature of detritus and a number of climatic factors given below. Chemical nature of detritus : The decomposition of detritus is slow if it contains lignin, chitin, tannins (phenolics) and cellulose. It is rapid if detritus possesses more nitrogenous compounds (like proteins, nucleic acids) and water-soluble reserve carbohydrates or sugars. The temperature above 25 o C favours the growth of microorganisms. Soil moisture is the most important climati
