Which of the following is false?
(I) The human liver fluke, a nematode parasite, depends on two intermediate hosts (snail and fish) to complete its life cycle.
(II) The malaria parasite needs a vector (mosquito) to spread to other parasite.
(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.
Text Solution
Verified by ExpertsD
Statement (II): True The malaria parasite (Plasmodium) requires a mosquito vector (specifically the female Anopheles) to transmit from one host to another.
Statement (III): True Female mosquitoes are generally not considered true parasites because they do not live on the host; they only take a blood meal to get the nutrients required for egg production (reproduction).
Statement (IV): True Brood parasitism (e.g., cuckoos laying eggs in a crow's nest) succeeds because the parasite's eggs evolve to mimic the host's eggs in color and pattern, preventing the host from identifying and ejecting them.
