Aspecies of malaria-carrying mosquito lives in a forest in which two species of monkey, a and b, coexist. species a is resistant to malaria, but species b is not. the malaria-carrying mosquito is the chief food for a type of bird in the forest. if all these birds were suddenly eliminated by hunters, which of the following would be an immediate observable consequence? (a) increased mortality in monkey species b(b) increased mortality in monkey species a(c) decreased mortality in monkey species b(d) decreased mortality in monkey species a

The correct answer is the increased mortality in monkey species B.

Explanation:

In the given question, it is mentioned that of the two species of monkeys, the species B is not resistant to mosquitoes carrying malaria, while the species A is resistant. Forr species B, the birds are playing an essential role, as they feed on the mosquitoes that carries malaria in their body. Thus, in case if all the mentioned birds get vanish due to overhunting by the hunters, the population of mosquitoes will increase at a rapid rate, which eventually would lead to species B monkeys getting affected with the disease. Thus, their chances of survival will become less due to rapid upsurge of mosquito population that carries the disease malaria with them.
