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) |
| 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. |

The following graph depicts changes in two populations (A and B) of herbivores in a grassy field. A possible reason for these changes is that:
| 1. | both plant populations in this habitat decreased |
| 2. | population-B competed more successfully for food than population-A |
| 3. | population-A produced more offspring than population-B |
| 4. | population-A consumed the members of population-B |
