Read the following statements and choose the correct option: 1. Bacterial and fungal enzymes degrade detritus into simpler inorganic substances, the process is called fragmentation 2. All the steps of decomposition takes place in interval of 10 minutes 3. Humification and mineralisation occur after decomposition in the soil 4. Humification leads to accumulation of a dark coloured amorphous substance called humus. 5.

Options

  1. AOnly 1 and 3 are incorrect
  2. BOnly 1 and 3 are correct
  3. CAll are incorrect except 5
  4. DOnly 4 is correct

Correct answer

D. Only 4 is correct

Step-by-step solution

Bacterial and fungal enzymes degrade detritus into simpler inorganic substances. This process is called as catabolism. All the steps of decomposition operate simultaneously on the detritus. Humification and mineralisation occur during decomposition in the soil. Humification leads to accumulation of a dark coloured amorphous substance called humus
