The answers to the questions related to the incidence of malaria in the village are
(a) Malaria is a life-threatening disease transmitted by mosquitoes.
- Frogs are their natural predators.
- Catching frogs would have caused a decline in its population.
- This in turn would have resulted in a rise in mosquitoes in the area.
- This increased the number of malaria cases.
(b) Frogs are an important constituent of the ecosystem.
- In this case, they are the natural control agents for mosquitoes.
- Drastic reduction in the population of one organism can affect the population of another, be it the prey or predator.
- In turn, this can lead to serious consequences like the one discussed here.
(c) Frogs can be used as a bio-control measure to control mosquito population.
- Suggestion can be made to avoid catching them extensively and/or exclusively from an area.
- There should be sufficient population of frogs left behind to produce more.
