Question

A phenomenon when a parasite parasitizes themselves is known as
A. Hyperparasitism
B. Parasitoids
C. Monoxenous parasitism
D. Polyxenous parasitism

Answer 1

Hint: A parasite is an organism that lives in or on other organisms and drives food from it. The organism from which it drives food is called the host and the organism that drives food is called the parasite.

Complete answer:
A parasite sometimes only gets food from the host and will not affect the host but in some, they can cause disease in the host and can lead to the death of the host. There are mainly three classes of parasites that cause disease in human beings they are- protozoa, helminth, ectoparasites.
> Hyperparasitism- Hyperparasite is a parasite whose host is also a parasite. It is usually an insect. Example: Apocrita lives as a parasite inside the Hymenoptera.
> Parasitoids- They are the parasites whose larvae live on or inside the host and ultimately kill it and feed on it. Most of the insect parasitoids are present in the order Hymenoptera.
> Monoxenous parasitism- monoxenous parasite is a type of parasite that develops inside a single host or it completes its life cycle inside only one host. They are sometimes hosting specifically. Some examples include Entamoeba histolytica that infects the human being.
> Polyxenous parasitism- The polyxenous parasites require more than one host to complete their life cycle.

A phenomenon when a parasite parasitizes itself is known as Hyperparasitism. So, the correct answer is option A.

Note:
There are other organisms that live inside or outside the host. But they do not cause any harm to the host. They are called the symbionts where their presence will help the host. Example- Zoomastigophora present in the stomach of termites helps them to digest cellulose.
