An obligate parasite, or holoparasite, is a parasitic organism that cannot complete its life-cycle without exploiting a suitable host. If an obligate parasite cannot obtain a host it will fail to reproduce.
A parasite is an organism that lives in another organism, called the host, and often harms it. It is dependent on its host for survival-it has to be in the host to live, grow and multiply. A parasite cannot live independently. Although a parasite rarely kills the host, in some cases it can happen.The parasite benefits at the expense of the host-the parasite uses the host to gain strength, and the host loses some strength as a result. Parasites, unlike predators, are usually much smaller than their host.ypes of parasites There are several types of parasites. Below are examples of some. Ectoparasite-a parasite that lives on the host's surface, examples include some mites and hair and body lice. Endoparasite-one that lives inside the host, examples include heartworm, tapeworm, and flatworms.
