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.
The parasite has a harmful effect on its "host" because it can cause a deadly disease or cause harmful pain.
because the "host"
might catch a deadly disease from the parasite
or it just might be very painful
A parasite can only live on a host. For example, a leech sucks a living animals blood to survive. Parasites do not benefit the host in any way
Parasites take the nutritional value of the proper nutrients in the intestinal tract and takes energy away from the body
The definition of parasitism is that one organism benefits and the other is harmed. The host usually becomes sick.
they bite them
The answer is parasitism, because parasites harm their host.
Fish can get parasites that harm them. Dogs can also get harmed by heartworms those are parasites. Humans can also be harmed by parasites. there are many parasites that can affect people.
It is rare, but yes sometimes. A few parasites don't directly kill their host, but make them do "careless things" that make it more likely the host will get eaten by the parasite's next host.
A "good" parasite doesn't kill it's host. It needs the host and killing it will kill the parasite. So it will allow the host to grow.
Viruses are similar to parasites because both require a host to survive and both destroy the cells in which they multiply (cause harm to the host).

it slowly kill the animal
it slowly kill the animal
By definition none do. Parasites harm the host that they prey upon.

The parasite keeps the host alive because the host is its source of everything. If the host dies, the parasite dies.
The Answer is ...IT CAN and IT CAN'TIt can kill a host when they are greater in number butIt can't kill a host when they are only few in numbers.BUT...... Parasites like leeches would be advantageous if they/it won't kill the host.-kiara
Usually, parasites are much smaller than the host is, whereas predators could be either small or larger than the prey. Parasites have a very high reproduction rate but the predators reproduce slowly.
The life or death of the host is no concern to the parasite. A parasite concern is 1. To find a host 2. Use the host for energy 3. Reproduce 4. Leave the old host and enter a new host for their perpetuation This happens in most of the cases like in TB, malaria, Typhoid, Cholera, African sleeping sickness, Ascariasis, Amoebiasis etc. But there are some parasites which don't kill host and the host doesn't have any effect of the parasites. Such a host is called Reservoir. The monkey is the reservoir for plasmodium vivax which cause malaria in humans. some parasites are useful and they live along with us as symboints.
Parasites and predators both exploit other animals, however a predator will immediately kill and eat its prey and a parasite will use a living host to survive, even if it does later kill its host.
