Which factor/s is responsible for controlling the rate of decomposition?

Options

  1. AClimatic factor
  2. BChemical composition of detritus
  3. CBoth A and B
  4. DNature of detritivores

Correct answer

C. Both A and B

Step-by-step solution

Decomposition is largely oxygen requiring process, the rate of decomposition is controlled by the chemical composition of detritus and climatic factors. Warm humid condition promotes the growth of microbes thus increases the rate of decomposition. If detritus is rich in nitrogen and water-soluble substance than the rate of decomposition is fast, if detritus is rich in lignin, cellulose than the rate of decomposition is slow.
