Vedclass · Answer

(C) Parasitism is a biological interaction where one organism (the parasite) lives on or inside another organism (the host) and derives nutrients at the expense of the host.$A$. Female Anopheles mosquito is a vector,not a parasite,as it does not live on or inside the host permanently.$B$. The human embryo is not a parasite; it is a developing offspring receiving nutrition through the placenta.$C$. Head louse ($Pediculus$ $humanus$ $capitis$) is an ectoparasite that lives on the human scalp and feeds on blood,causing irritation and harm to the host.$D$. Cuckoo laying eggs in a crow's nest is an example of brood parasitism,but the question specifically asks for the organism categorized as a parasite in a standard sense. However,in the context of biological interactions,the head louse is the most direct example of an ectoparasite.
