| Due to some reasons, if there is a huge fall in the population of species of butterflies, what could be its likely consequence/consequences? |
| 1. Pollination of some plants could be adversely affected. |
| 2. There could be a drastic increase in the fungal infections of some cultivated plants. |
| 3. It could lead to a fall in the population of some species of wasps, spiders and birds. |
| Select the correct answer using the code given below: |
A) Only 1

Correct Answer: C
