Q. I. The human liverfluke, a nematode parasite, depends on two intermediate hosts (snail and pig) to complete its life cycle II. The malaria parasite needs a vector (mosquito) to spread to other hosts III. The female mosquito is not considered parasite, however it needs our blood for reproduction IV. In case of brood parasitism, the eggs of parasitic birds ($e.g.,$cuckoo) are not detected and ejected from the nest because of parasite’s eggs resemble the hosts eggs in morphology and colour V. A population of frogs protected from all predators would increase indefinitely. Which statements are correct?

A) I and II
B) II and III
C) III, IV and V
D) I, II, III and IV
Explanation

A population of frog protected from all predator would not increase indefinitely because nature’s resources are limited. Beyond a carrying capacity the population would not increase because it is the maximum number of population which can be sustained by the habitat
