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:

1. 1 only
2. 2 and 3 only
3. 1 and 3 only
4. 1, 2 and 3

Explanation

Option (c) is correct

• Butterflies are important pollinators for many plants. A decline in their population can disrupt the pollination process, leading to reduced plant reproduction. While some insects play a role in controlling plant diseases, butterflies do not significantly impact fungal infections in crops. Butterflies are part of the food chain and serve as prey for various species. A decline in butterfly populations could affect these predators.
