Because it would deprive itself of its food-source. Parasites thrive by feeding off a 'host' - rather than catching their own food. If they kill off the host - they either have to find another host - or die !
A parasite doesn't kill it's host because if it's host dies, the parasite then also dies because now, the parasite has no where to live and nothing to feed off of!!!
Actually, many parasites do kill their host. The key is that parasites do not want to kill their host until after they have found a new host. After a parasite finds a new host, it no longer "cares" if the old host dies or lives. Diseases (parasites) that are transmitted to a new host very easily often kill their hosts. Diseases that are NOT transmitted easily to a new host often will make you sick, but will not kill you; these diseases want you up, walking around, and interacting with as many people as possible so that they can be picked up by a new host.
One species of parasite that completely deliberately kills one of its 3 hosts is Dicrocoelium dendriticum, a lancet fluke. Its hosts are:
Because at that point it can no longer exploit the host's resources. It will have to leave the host (or become dormant inside, and wait for it to decompose) or die with it. It also hinders the spreading of the parasite species.
Because they reproduce so quickly! One parasite make 1,000 it is very hard! Just got to try HARD, and possibly continuously
Because killing it's host will inadvertently kill itself when it runs out if resources.
yes. if water is dirty, it could contain parasites. parasites are mainly found in dirt and raw fish. if water is dirty, and you drink it, it is rare but you can get a parasite. most parasites are killing machines, so if you aren't killed by it, you will probably suffer from a major injury.
Because if it can kill a cow, approximitly it will be hard to kill.
Most parasites don't kill their hosts, because it doesn't take all the nutrients from the host. It only needs a certain amount of nutrients. So it will cause some bad effects on host, but it won't cause complete destruction.
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.
No sir or ma'am mosquito do carry parasites so you need to use bug spray when you are around them because they carry they are one of the most common transportation for parasites so WATCH OUT A MOSQUITO!!
Lions are carnevarous animals , so they live on flesh of animals they kill. And the lioness does most of the hunting and the hard work.any kind of meat
so hard that he could knockout anybody in 1 punch and kill them
I want to kill myself, this math is so freaking hard dude.
This is because they are harsher on the body. It takes more to kill off these kinds of diseases so they are more harmful to the body.
Cheetahs are carnivores, so they only bite hard enough to kill their next meal.
A colossus is a giant monster that is so hard to kill. The only way you could actually kill one is stabbing it in a certain area. But the only hard thing about that is that THEY ARE NOT REAL.
no its so hard that it could kill you
