parasite/host
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.
It harms a parasite to have its host die because the host is what the parasite depends on. If the host dies then the parasite will have nothing to depend on and die.
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.
A parasite lives on another organism (host) at the expense of the host. The host is being harmed while the parasite is benefiting.
An obligate parasite can only live inside a cell. This includes viruses and intracellular bacteria. A facultative parasite can live inside or outside of a cell.
