Match List I with List II List I (Process of decomposition) List II (Explanation) (A). Leaching (I). Bacterial and fungal enzymatic degradation of detritus (B). Catabolism (II). Accumulation of partially decomposed dark colloidal substance (C). Humification (III). Degradation of humus by microbes to release inorganic nutrients (D). Mineralization (IV). Percolation of water-soluble inorganic nutrients into soil Choose

Options

  1. A(A) - (IV), (B) - (I), (C) - (II), (D) - (III)
  2. B(A) - (II), (B) - (IV), (C) - (I), (D) - (III)
  3. C(A) - (I), (B) - (II), (C) - (IV), (D) - (III)
  4. D(A) - (III), (B) - (IV), (C) - (I), (D) - (II)

Correct answer

A. (A) - (IV), (B) - (I), (C) - (II), (D) - (III)

Step-by-step solution

Leaching is the process by which water-soluble inorganic nutrients percolate down into the soil horizon and get precipitated as unavailable salts. Thus, (A) matches with (IV). Catabolism involves bacterial and fungal enzymes degrading detritus into simpler inorganic substances. Thus, (B) matches with (I). Humification leads to the accumulation of a dark coloured amorphous substance called humus that is highly resistant to microbial action and undergoes decomposition at an extremely slow rate. Thus, (C) matches with
