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.
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.
vector is usually is the arthropodes carrying the parasites such as mosquitoes.
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.
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.)
Just the areas you are restricted to & there are some small differences on the tests.
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.
Every disease is an illness but not every illness is a disease (A disease is not a virus, parasite, etc but an illness could be)
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.
The host provides shelter or food or even protection for a parasite. The parasite uses the host for food, etc.
A parasite is an organism that lives in or on another organism (host) and feeds off its resources without necessarily killing it. A carnivore is an organism that primarily feeds on meat from other animals. While both can be predatory, parasites rely on a host for survival, while carnivores actively hunt and consume prey.
