Q. No.Given below are two statements : One is labelled as Assertion (A) and the other is labelled as Reason (R).
Assertion (A):
Connell's elegant field experiment showed that on the rocky sea, the larger and competitively superior barnacles dominate the intertidal area and exclude the smaller barnacles from that area.
Reason (R):
Generally, herbivores and plants appear to be more adversely affected by competition than carnivores.
In the light of the above statements, choose the correct answer from the options given below:
1.
Both (A) and (R) are True and (R) is the correct explanation of (A)
2.
Both (A) and (R) are True but (R) is not the correct explanation of (A)
3.
(A) is True but (R) is False.
4.
(A) is False but (R) is True.

Assertion (A) and the other is labelled as Reason (R).
In the light of the above statements, choose the correct answer from the options given below:
Assertion (A) and the other is labelled as Reason (R).
| Assertion (A): | The interaction, in which one species benefits and the other is neither harmed nor benefitted, is known as commensalism. |
| Reason (R): | Egrets always forage close to where the cattles are grazing, otherwise it is difficult for the egrets to find the insect and catch. |
