Release of inorganic nutrients by the activity of microbes in soil III. Breaking down of complex organic matter into inorganic substances. IV. Dead remains of plants and animals including fecal matter Choose the correct answer from the options given below:
- A.A-IV, B-III, C-I, D-II
- B.A-III, B-IV, C-II, D-I✓
- C.A-I, B-II, C-III, D-IV
- D.A-III, B-II, C-I, D-IV
Correct Answer
(B) A-III, B-IV, C-II, D-I
Solution & Explanation
Answer: (B) Decomposition = breaking down of complex organic matter into inorganic substances (III); Detritus = dead remains of plants and animals including fecal matter (IV); Mineralisation = release of inorganic nutrients by microbial activity in soil (II); Humification = accumulation of dark coloured amorphous colloidal substance, humus (I). This gives A-III, B-IV, C-II, D-I = option (2), i.e. (b). NCERT Reference: Ch 12, p.207 — “down complex organic matter into inorganic substances”
