What is the definition of parasite?
-A parasite is an organism that benefits from a close prolonged relationship with its host, which is harmed.
The parasite grows, feeds, or uses shelter of the host organism (including the host itself) contributing negatively to the relationship.
== == * A parasite is an organism that has a deleterious symbiotic relationship with another organism or host species. The parasite usually lives on or in the host and needs the host for energy and nutrients to survive. A flea or tick is a parasite. Bacteria can be parasitic. Mistletoe is a parasite. Parasites sometimes cause the eventual death of the host although not always, and this can lead to the parasites demise if it cannot leave or find a new host. On a humorous note I like to think of lawyers as parasites. * From Latin sēnsū lātō ("'in the broad sense'"). A parasite is an organism that has a deleterious symbiotic (Symbiosis (Gr. for "living together")) relationship with another organism or "host" species during one, several, or all of the stages of it's life cycle. The parasite usually lives on or in the host and needs the host for energy and nutrients to survive. An organism can(but not always) have multiple hosts sometimes a new one specific for a particular stage in the parasites life cycle. Parasitism is a special case of symbiosis in which only one species benefits. Mutualism and commensalism are the other two cases.
* From Latin sensu stricto ("in the narrow sense").From Latin parasitus < Greek παράσιτος (parasitos), "'person who eats at the table of another'")
* 1. (biology) A (generally undesirable) living organism that exists by stealing the resources produced/collected by another living organism. Lice, fleas, ticks and mites are widely spread parasites. 2. (pejorative) A person who relies on other people's efforts and gives little back (originally a sycophant). http://en.wiktionary.org/wiki/parasite
* Parasite: An organism that absorbs nutrients from the body fluids of living hosts. * Parasitism: A symbiotic relationship in which the symbiont(parasite) benefits at the expense of the host by living either within the host(endoparasite) or outside the host(ectoparasite). -Campbell, Reece, Mitchell. Biology 5th Edition (Glenview, Illinois: Addison Wesley Longman, 1999)

a parasites lives in a close relationship with another organism it's host and causes it harm
No. Although its biological behavior is like that of a parasite, it is not, by definition, a parasite. This isn't really a useful answer, but it's not really a useful question. It's like saying your newborn child doesn't think George Bush is a very good President. Well, he doesn't think he's a bad President either. Calling something a parasite describes a relationship where one organism lives at the expense of another. And the embryo does…
How can you tell someone who is a manipulator liar that they fit the definition of what a human parasite is?
When a parasite is growing and multiplying within or on a host, the host is said to have and infection. An infection may or may not result in overt disease. An infectious disease is any change from a state of health in which part or all of the host body is not capable of carrying on its normal functions due to the presence of a parasite or its products.
there is no type of parasitism that doesnt harm the host. parasitism by definition means: an organism living within another larger organism where the parasite benefits from the host and the host is harmed (diseases). when the parasite is benificial to the host (in case of tryconymphs in coacroaches that helps them to digest cellulose) the relation is called symbiotic relation and not parasitism
By definition a parasite is harmful. Any number of diseases that you can think of caused by bacteria, viruses, worms, lice or amoebae are parasites. Their job is not to live with you but to use you as a source of food and to make more parasites like themselves. Some parasites do live a long time on you or in you but they always cause harm.
Parasitism is the relationship between the host and the parasite in which the parasite benefits, but the host is harmed. Parasitism is the word given to describe the action of a parasite. A parasite is an organism that lives with another organism (symbiosis.) However, a parasite only takes from its host, it does not contribute to the relationship in such a way that its host benefits. Some parasites are harmless, but others will parasitize until…
