Question

Match List I with List II. 

	List I  (Interacting species)		List II (Name of interaction)
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-IV, D-III
• B. A-III, B-IV, C-I, D-II
• C. A-II, B-III, C-I, D-IV
• D. A-I, B-II, C-III, D-IV

Answer 1

The Correct Option is D

To match List I with List II, we need to understand the types of biological interactions described:

• Competition: This occurs when two species vie for the same resources. Example: Leopard and Lion in a habitat.
• Brood parasitism: A strategy where a bird lays its eggs in the nest of another species. Example: Cuckoo laying eggs in Crow's nest.
• Mutualism: An interaction where both species benefit. Example: Fungi and plant roots in Mycorrhizae.
• Commensalism: One species benefits while the other is unaffected. Example: Cattle egret and a Cattle.

The correct matches based on these definitions are:

• A (Leopard and Lion) with I (Competition)
• B (Cuckoo and Crow) with II (Brood parasitism)
• C (Fungi and root) with III (Mutualism)
• D (Cattle egret and Cattle) with IV (Commensalism)

Therefore, the correct option is:

A-I, B-II, C-III, D-IV
