Which of the following can accelerate the rate of decomposition of the detritus?

Options

  1. AIf the detritus contains lignin, chitin, tannins and cellulose
  2. BIf the detritus is present in acidic soil
  3. CIf the moisture and aeration are at optimum
  4. DIf the temperature is below 10 ° C

Correct answer

C. If the moisture and aeration are at optimum

Step-by-step solution

Factors Affecting Decomposition: The rate of decomposition of detritus is controlled by the chemical nature of detritus and a number of climatic factors given below. a) Chemical nature of detritus. Decomposition of detritus is slow if it contains lignin, chitin, tannins (phenolics) and cellulose. It is rapid if detritus possesses more of nitrogenous compounds (like proteins, nucleic acids) and water-soluble reserve carbohydrates or sugars. b)Temperature and c) soil moisture is the most important climatic factors th
