Question

Which of the following can be categorized as a parasite in true sense?

• A. The female Anopheles mosquito sucks blood from human
• B. Human foetus developing in uterus draws nourishment from mother
• C. Head lice lives on human scalp and lays eggs on hair
• D. The cuckoo lays eggs in crows nest for subsequent parental care

Answer 1

The correct option is C Head lice lives on human scalp and lays eggs on hair

The parasite is defined as the organism which survives on the body of the host organism for food and space to survive. The Anopheles mosquito feeding on the blood of animals, the human fetus developing in the womb of the mother, and derives the nourishment from the mother and the cuckoo laying eggs in the crow's nest are the interactions of the living organisms. The head lice living on the human scalp and lays eggs on hair cannot survive without this habitat and completely depends on the host.

Thus, the correct answer is option C.
