Bacteria. A virus is a non-living thing. Bacteria is a living thing.
Viruses are similar to parasites because both require a host to survive and both destroy the cells in which they multiply (cause harm to the host).
They are obligate in the sense that they cannot replicate outside of a host cell. To make a copy of itself, a virus must first enter a cell (intracellular), hijack the machinations of said cell (parasitic behavior) and then copy itself.
Of course they have. Only some virus lack them
This is a parasite, the human pin worm.

A host.
A virus or a parasite.

A virus is considered a parasite because it attaches to a cell and kills it.
a tapeworm is neither, it is a living organism which lives in the intestine. but if any, it COULD be classed as a virus.

Yes virus cannot survive on the atmosphere beside living in host. It is a kind a neutral parasite which acts like a non living but works on the living cell
A parasite is an organism that lives in or on another organism (the host) and benefits by deriving nutrients at the host's expense. A virus is a form of parasite.

a virus can ony reproduce inside a living cell that surves as a host. A Host is living thing that a virus or parasite lives on or in . Using a host's cell as a tiny factory , the virus forces the host to make viruses rather than healthy new cells.
