Question

Q. Consider the following pairs:

Interspecific Interactions	Example
1. Commensalism	Golden jackal following Tigers
2. Ammensalism	Birds living is hollow trees
3. Mutualism	Interaction between lion and deer

Which of the above pairs is/are correctly matched?

• A. 1 only
• B. 2 only
• C. 2 and 3 only
• D. 1, 2 and 3 only

Answer 1

The correct option is A 1 only

Explanation:

Pair 1 is Correct: Commensalism is the interaction in which one species benefits and the other is neither harmed nor benefited. A Golden jackal follows Tiger and eats the leftover animals killed by Tigers. However, the tiger does not get any benefit or harm from it.

Pair 2 is incorrect: Ammensalism is a relationship between organisms of different species in which one organism is inhibited or destroyed while the other organism remains unaffected. Birds that live in the hollows of trees are commensal. Their presence generally does not harm the tree, but the tree provides the bird with shelter and protection.

Pair 3 is incorrect: Mutualism is an interaction that confers benefits on both the interacting species. Tiger and Lion do not benefit each other but are each other's competition.
