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.

Butterflies play a critical role in the ecosystem by helping in pollination. A decline in their population could indeed adversely affect the pollination of some plants, which is why option 1 is correct. Regarding option 2, butterflies do not have a direct connection with preventing fungal infections in plants. It`s more related to the health of the plant and the micro-environment, rather than butterflies. Hence, option 2 is incorrect. For option 3, some species of wasps, spiders, and birds feed off butterflies, meaning a decrease in butterfly populations could potentially lead to a fall in the population of those species as well. Therefore, the correct answer is `1 and 3 only`, represented by option 3. It`s important to understand that every organism plays an interconnected role in the ecosystem, and the decline of one can affect the others.
