Question: 148 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 Mycorrtizae | III. Mutualism |
| D. A cattle egret and a Cattle in a field | IV. Commensalism |
Choose the correct answer from the options given below:
(1) A-III, B-IV, C-I, D-II
(2) A-II, B-III, C-I, D-IV
(3) A-I, B-II, C-III, D-IV
(4) A-I, B-II, C-IV, D-III
Answer: Option (3)
Explanation:
Leopard and lion living in the same forest or grassland compete for similar prey and territory,
so their interaction is competition.
Cuckoo lays its eggs in the nest of crow and relies on the crow to incubate and raise its young,
which is known as brood parasitism.
In mycorrhizae, fungi and roots of higher plants both benefit from each other,
making the interaction mutualism.
Cattle egret feeds on insects disturbed by grazing cattle while the cattle are neither harmed nor benefited,
which represents commensalism.
Thus, the correct matching is A-I, B-II, C-III and D-IV.
