A parasitic organism is a life-form that can not sustain life without another living creature or plant.
It often lack the ability to "digest" food and utilize a host by draining its nutrients.
Some parasites do however digest food, they just use a host as food, eating away on the host or eating away on the food the host have eaten.
Most if not all are defined as parasites because they can not live for long outside or away from a host of which is its feeding ground.
A parasite is bad for a host because there are normally no benefits to the host from them.
A parasitic organism is an organism that lives in or on another organism (the host) and obtains nutrients at the hostβs expense. Parasites can cause harm to the host by feeding on its tissues, disrupting its normal functions, or spreading diseases. Examples of parasitic organisms include tapeworms, ticks, and some types of bacteria.
One example of hyperparasitism is when a parasitic wasp lays its eggs inside a host that is already infected with parasitic larvae. Another example is when a fungus infects a parasitic organism that is already living on a host organism.
Parasitic interactions involve one organism benefiting at the expense of another organism. The parasite benefits by obtaining nutrients or shelter from the host, while the host is harmed in the process. Parasites can be external, like ticks and fleas, or internal, like tapeworms and parasitic fungi.
paracitism
Round worms are heterotrophic, obtaining their nutrition by feeding on organic matter in their environment. Plasmodium is a parasitic protist that obtains its nutrition by feeding on the blood of its host organism.
Examples of parasitic organisms include ticks, fleas, tapeworms, and malaria-causing Plasmodium parasites. These organisms rely on a host organism for their survival and can cause harm or disease to their hosts.
free living
Organisms can be grouped as free-living or parasitic. A parasite is an organism which lives in or on another organism, from which it obtains its food. Since humans do not do this they are not parasitic, and so must be free-living.
the parasites which complete their life cycles in one host
A zooparasite is any organism which is parasitic to an animal.

predator
One example of hyperparasitism is when a parasitic wasp lays its eggs inside a host that is already infected with parasitic larvae. Another example is when a fungus infects a parasitic organism that is already living on a host organism.
It's called a parasitic relationship.

parasitic worms
Parasitic describes one organism that feeds on the other from within.
A parasitic worm is a worm that feeds on another organism, its 'host'. For example a tape worm. It latches onto the intestine of humans.
