Parasites feed off their hosts. Predators feed off their prey. Difference is that parasites want to keep their hosts alive so they can continue to feed off them.
Host's
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.
Parasitism involves one organism (parasite) living off of another (host) in a harmful manner but without killing the host. Predation involves one organism (predator) killing another (prey) for food.
Parasites and predators are alike in the fact that they both depend on another living thing to survive. A predator kills its prey for nourishment while parasites drain their host slowly.
They depend on other living organisms to live.
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.
Parasites and predators are quite similar, however, an animal is called a parasite if it only eats part of another animal and its victim continues to live. Mosquitos are micropredators.orA parasite feeds off a host without meaning to kill it while a predator feeds off a prey which it kills intentionally.orThe main difference between a parasite and predator is....A parasite is an organism which depends upon its host for food, shelter and reproduction.Whereas the predator kills its prey and eats it. It doesn't depend for shelter or reproduction except for food.Predator and parasite are similar in their feeding habits. Both of them depend upon others for their food. Infact we the humans are also called predators which is not accepted by many scientists.Parasites are smaller than host and don't kill host eg. mosquito on man .Predators are larger than prey and kill it eg lion and deer .
A parasite eats you alive and could kill you if not treated, and on the other hand, predators stalk their prey. They are both similar in more than a few ways, but i will tell you one thing, they both stick with the prey they are after.
Prey, Predators, and Parasites
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.
Predation and parasitism are similar because they both involve one organism feeding off of other organisms. They're different because predators kill their prey, while parasites may harm their hosts but won't kill them.
Predation is different from parasitism in that predators kill their prey before consumption. Parasites must keep their hosts alive in order to continually feed off of them.
