| LIST-I Pollution Indicator | LIST-II Example |
|---|---|
| A. Macrofauna | I. Plants |
| B. Mesofauna | II. Rabbit |
| C. Microfauna | III. Earthworm |
| D. Macroflora | IV. Protozoa |
Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → A - II, B - III, C - IV, D - I
Soil organisms used as pollution indicators are grouped by body size. Macrofauna (A - II) are the largest animals of the group, such as a rabbit and other burrowing vertebrates. Mesofauna (B - III) are the intermediate invertebrates such as the earthworm. Microfauna (C - IV) are the microscopic animals, typically protozoa and nematodes.
Macroflora (D - I) is the plant side of the classification, so it matches plants.
