Match List-I with List-II

Choose the correct answer from the options given below:

(A)-(IV), (B)-(I), (C)-(II), (D)-(III)

The correct answer is Option (3) → (A)-(IV), (B)-(I), (C)-(II), (D)-(III)

A. Parasites that feed on the external surface of the host organism are called ectoparasites. The most familiar examples of this group are the lice on humans and ticks on dogs. Cuscuta, a parasitic plant that is commonly found growing on hedge plants, has lost its chlorophyll and leaves in the course of evolution.

B. Brood parasitism in birds is a fascinating example of parasitism in which the parasitic bird lays its eggs in the nest of its host and lets the host incubate them.e.g. the movements of the cuckoo (koel) and the crow during the breeding season (spring to summer) and watch brood parasitism in action.

C. The life cycles of parasites are often complex, involving one or two intermediate hosts or vectors to facilitate parasitisation of its primary host. The human liver fluke (a trematode parasite) depends on two intermediate hosts (a snail and a fish) to complete its life cycle. The malarial parasite needs a vector (mosquito) to spread to other hosts.

D. Plasmodium (protozoan parasite inside humans, transmitted by mosquito). The mosquito itself is not the parasite, but the vector.
