Decomposition Processes Matching Solution
This question requires matching four key decomposition processes (List - I) with their corresponding functions or descriptions (List - II).
Matching the Processes
- Leaching (A): This process involves the downward movement of water-soluble substances through the soil profile. Option IV, "Water soluble inorganic nutrients go down into the soil and get precipitated," accurately describes leaching.
- Catabolism (B): In the context of decomposition, catabolism refers to the enzymatic breakdown of complex organic matter by microorganisms into simpler substances. Option III, "Bacterial and Fungal enzymes degrade detritus into simpler inorganic substances," fits this description.
- Humification (C): This process leads to the formation of humus, a stable, dark-colored organic material rich in nutrients. Option II, "Accumulation of a colloidal dark coloured amorphous substance, which is a reservoir of nutrients," defines humification.
- Mineralization (D): This is the final stage where organic matter is broken down into inorganic nutrients that plants can utilize. Option I, "Degradation of humus by microbes to release inorganic nutrients," correctly describes mineralization.
Correct Matching
Based on the analysis, the correct matching is:
- A - IV
- B - III
- C - II
- D - I
This corresponds to Option D.
