Given below are two statements:Statement I: Decomposition is a process in which the detritus is degraded into simpler substances by microbes.Statement II: Decomposition is faster if the detritus is rich in lignin and chitin.In the light of the above statements, choose the correct answer from the options given below:

  1. A
    Both Statement I and Statement II are correct
  2. B
    Both Statement I and Statement II are incorrect
  3. C
    Statement I is correct but Statement II is incorrect
  4. D
    Statement I is incorrect but Statement II is correct

Solution & Step-by-step Explanation

1. Statement I is correct: Microbes (decomposers) break down complex organic matter into inorganic substances like , water, and nutrients.2. Statement II is incorrect: The rate of decomposition is largely determined by the chemical composition of detritus. Decomposition is slower if detritus is rich in lignin and chitin, and faster if it is rich in nitrogen and water-soluble substances like sugars.
