A parasite needs a host to live in, typically a living one. A pest, on the other hand, is just something that makes you uncomfortable.
The main difference is that a carnivore will eat a dead animal, while a parasite will feed of a living animal.
A fluke is a parasite, and a flounder is a fish
To be simple:The flea is the parasite and the dog is the host.
Parasites feed off of another organism. Pests are annoying.
vector is usually is the arthropodes carrying the parasites such as mosquitoes.
An internal parasite feeds with his entire body inside the surface (epithelium, for animals) of the host, while an external parasite feeds with part of, or whole body standing outside the host's surface.
There is no difference they are both the same like the rabbit is a feral animal/pest to Australia.
Im assuming that you havent ever even hear the definition of parasite or host, but the HOST is what the PARASITE LIVES ON . aka it means the parisite takes everything it needs from the host.
parasite is a animal but bacteria is a prokaryotic cell which may have free existence.
a parasite is the organism that feeds off their prey but the prey gets nothing in return a symbiont fuses with the holder without harm or bodily harm
A host is an organism that the parasite lives on. In other words the parasite may use the host's resources in a negative way. For example: A tick living off the blood of a human. The tick is the parasite and the human is the host. The tick lives off the blood of the human.
The opposite status is a "host" (the victim or target of a parasite).The opposite type of symbiote from a harmful or parasitic one would be a beneficial symbiote, a mutualist organism. (When internal, these are called endosymbionts.)
