Two butterfly species are competing for the same nectar of a flower in a garden. To survive and coexist together, they may avoid competition in the same garden by:
1. feeding at the same time.
2. choosing different foraging patterns.
3. increasing time spent on attacking each other.
4. predating on each other.

| Reason (R): | Interactions between organisms are not relevant for the study of ecology. |
| 1. | Both (A) and (R) are false. |
| 2. | Both (A) and (R) are true but (R) does not explain (A). |
| 3. | (A) is true but (R) is false. |
