Read the following statements and choose the correct option: 1. Decomposition does not require oxygen. 2. The rate of decomposition is controlled by chemical composition of detritus and climatic factors 3. Decomposition rate is slower if detritus is rich in cellulose 4. Decomposition rate is quicker, if detritus is rich in nitrogen and water-soluble substances like sugars

Options

  1. Aall are correct
  2. BOnly 1 and 3 are incorrect
  3. C1,2,3 are correct
  4. DOnly 2 and 4 are incorrect

Correct answer

B. Only 1 and 3 are incorrect

Step-by-step solution

Decomposition is largely an oxygen-requiring process. The rate of decomposition is controlled by chemical composition of detritus and climatic factors. In a particular climatic condition, decomposition rate is slower if detritus is rich in lignin and chitin, and quicker, if detritus is rich in nitrogen and water-soluble substances like sugar
