What is Parasitism?

Parasitism is a type of symbiotic relationship that exists between two organisms, in which one organism, known as the parasite, benefits at the expense of the other, known as the host. This relationship can be either temporary or permanent, and can take different forms such as predation, mutualism, and parasitism.

Types of Parasitism

There are two main types of parasitism: ectoparasites, which live on the surface of their hosts, and endoparasites, which live inside their hosts.


Ectoparasites are parasites that live on the surface of their hosts, including fleas, ticks, lice, and mites. These parasites feed on their host’s blood, skin, and other bodily fluids, and can cause disease, irritation, and discomfort.


Endoparasites are parasites that live inside the body of their hosts, including worms, protozoa, and viruses. These parasites are usually transmitted through contaminated food or water, and can cause a variety of illnesses and diseases.
