Given below are two statements : One is labelled as 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): | 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. |
| 1. | Both (A) and (R) are True and (R) is the correct explanation of (A) |
