What is Parasitism?

Parasitism is a type of symbiotic relationship in which one organism, the parasite, benefits at the expense of another organism, the host. 

The parasite typically lives on or inside the host & derives its nutrition from the host's body. 

Parasites can have a range of effects on their hosts, ranging from mild irritation to severe disease & even death. 

Parasites can be classified into several groups based on their interactions with their hosts. 

Endoparasites live inside the host's body, while ectoparasites live on the surface of the host's body.

 Obligate parasites require a host to complete their life cycle, while facultative parasites can live independently of the host if necessary. 

Examples of parasites include tapeworms, lice, fleas, & certain species of bacteria & viruses.
