Select the incorrect statement w.r.t decomposition.

Options

  1. ABacterial and fungal enzymes degrade detritus into simpler inorganic substances in a process is called catabol
  2. BHumus is less resistant to microbial action and undergoes decomposition at an extremely slow rate.
  3. CBy the process of leaching, watersoluble inorganic nutrients go down into the soil horizon and get precipitate
  4. DDecomposition is largely an oxygen-requiring process.

Correct answer

B. Humus is less resistant to microbial action and undergoes decomposition at an extremely slow rate.

Step-by-step solution

Humification leads to accumulation of a dark coloured amorphous substance called humus that is highly resistant to microbial action and undergoes decomposition at an extremely slow rate. Being colloidal in nature it serves as a reservoir of nutrients.
