living by exploitation of others.
An interaction in which one organism feeds on another organism, harming (but generally not killing) it.
The condition of living in or on another organism (the host) to obtain food, without killing that host but usually debilitating it (noun); but see also the term parasitoidism.
Parasitism - The act of one organism establishing itself upon or within a host organism and feeding off its host. Contrast with commensalism.
Form of symbiosis where one organism is living at the expense of another host organism. Parasitic organisms can be either endoparasites (within the host) or ectoparasites (outside the host).
a symbiosis in which one partner benefits, to the detriment of the other
A symbiotic relationship in which one species benefits, and the other species is harmed Generally, the species that benefits (the parasite) is much smaller than the species that is harmed (the host)
One benefits while the other is ha...
A type of symbiotic relationship in which one species (parasite) benefits from the relationship at the expense of the other (host), causing it harm and maybe even death.
a type of symbiosis in which one population benefits while the other is harmed.
A relationship between two organisms, where one uses the other as a host, usually injuring it but not killing it quickly.
the relation between two different kinds of organisms in which one receives benefits from the other by causing damage to it (usually not fatal damage)
A relationship in which one organism, a parasite, secures its nourishment by living on or inside a host organism at the expense of its host
A relationship where one organism (called a parasite) lives off another (called a host). It may live on or inside the host. A parasite does not help the host. Sometimes it hurts the host, sometimes it does not. See the Relationships page for more explanation.
A relationship in which an organism of one kind lives in, on, or in intimate association with an organism of another kind, at whose expense it obtains food and usually other benefits.
par-a-si-tizm A symbiotic relationship in which one member harms the other. 435
One benefits while the other is harmed. Example: A flea is a parasite on a dog. The flea, benefits by drinking the dog's blood, but the dog, by losing blood and acquiring disease and discomfort, is harmed.
The phenomenon of the growth of one organism, the parasite, at the expense of another, the host.
the mode of life of a parasite, i.e., as between it and its host.
similar to predation in that one species benefits from the relationship and the other is harmed; differs from predation in that parasitism generally not fatal to adversely affected organism.
A form of symbiosis in which the population of one species benefits at the expense of the population of another species.
Interaction between species in which one organism, called the parasite, preys on another organism, called the host, by living on or in the host. See host, parasite.
one of several types of symbiotic relationships between the individuals of two (or more) different species In a parasitic relationship one species benefits, the other is harmed (see symbiosis).
Biological interaction between species where a parasite species feeds on a host species.
a type of ecological symbiosis in which one organism (the parasite) drains nutirents from another (the host), typically while living on or within the host. Sometimes can cause the death of the host but this usually occurs when a parasite attacks a novel host that has not had time to coevolve any defenses)
The relationship in which an organism lives in or on an organism and feeds from it
A symbiotic relationship in which one organism, the parasite, benefits at the expense of the other organism, the host.
Parasitism is arelationship between two organisms in which one organism benefits at the other organism's expense. Lice are an example of a parasite that affects many animals. Parasitism is a type of symbiosis.
Parasitism is one version of symbiosis ("living together"), a phenomenon in which two organisms which are phylogenetically unrelated co-exist over a prolonged period of time, usually the lifetime of one of the individuals. The requirement for a prolonged interaction precludes predatory or episodic interactions (such as a mosquito feeding on a host), which are usually not seen as symbiotic relationships. Symbiosis encompasses commensalism ("eating at the same table", wherein two organisms co-exist in the same space, and one organism benefits while neither harming nor helping the other), through mutualism (wherein both species benefit from the interaction) to parasitism, wherein one organism, usually physically smaller of the two (the parasite) benefits and the other (the host) is harmed.
