Detailed explanation-1: -A parasite is an organism that lives on or in a host organism and gets its food from or at the expense of its host. There are three main classes of parasites that can cause disease in humans: protozoa, helminths, and ectoparasites. Entamoeba histolytica is a protozoan. A microscope is necessary to view this parasite.
Detailed explanation-2: -Parasites are strongly dependent on host suitability for successful reproduction. Some parasites may prosper using a broad range of hosts, while others specialise on one particular host species1. For generalist parasites, it is very important to select host species that maximize their fitness.
Detailed explanation-3: -In contrast, parasites that live inside their hosts are known as endoparasites (Figure 2B).
