What is the definition of parasition?

Answer 1

-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 parasite is an organism that lives on or inside another organism to the detriment of the host organism' -Wikipedia For a list of human parasites: http://en.wikipedia.org/wiki/List_of_parasites_(human) Examples of parasites: 1) Animal/insect parasites [aphids] 2) Plant parasites



a parasites lives in a close relationship with another organism it's host and causes it harm

Answer 2

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 the death of their host. This usually results in the parasite's death but if it has already reproduced, this is of no consequence to it.

Examples: A tick feeding off a dog. (The tick takes blood from the dog - energy and food - but does not give anything to the dog in return.)

Mistletoe feeding off a tree. (The mistletoe has leaves and makes its own food, but takes water and sometimes sap from its host.)

Answer 3

Something that feeds off another animal.
