NEET2023Biology
Q.
Match List I with List II:
| List I (Interacting species) | List II (Name of interaction) |
|---|---|
| A. A Leopard and a Lion in a forest/grassland | I. Competition |
| B. A Cuckoo laying egg in a Crow's nest | II. Brood parasitism |
| C. Fungi and root of a higher plant in Mycorrhizae | III. Mutualism |
| D. A cattle egret and a Cattle in a field | IV. Commensalism |
Choose the correct answer from the options given below:
- A
A-I, B-II, C-III, D-IV
- B
A-I, B-II, C-IV, D-III
- C
A-III, B-IV, C-I, D-II
- D
A-II, B-III, C-I, D-IV
Solution
Two top carnivores share prey — competition (A–I). The cuckoo's strategy of leaving eggs in another bird's nest is the textbook example of brood parasitism (B–II). Mycorrhizal fungi exchange phosphorus for plant carbohydrates — mutualism (C–III). The cattle egret eats insects flushed up by grazing cattle, benefitting itself while the cattle are unaffected — commensalism (D–IV).
