The host.
A virus does not have a metabolism. To reproduce, a virus takes control of a living cell, forcing the cell to make copies of the virus. All energy is provided by the cell.
A virus is debatably not a living thing, it stores no energy and "tricks" the cell into expending its own energy which the virus then uses for its "evil deeds"
it is not made of cells (A+)
There is no other living thing that requires a virus in order to reproduce.
bacteria
parasites

Bacteria. A virus is a non-living thing. Bacteria is a living thing.
A virus uses the host energy making organelles to produce its' energy requirements.
viruses dot need energy.
A virus uses the host energy making organelles to produce its' energy requirements.
The flu virus is a non-living thing, so it doesn't have its own energy source. To reproduce, it hijacks the cells of a living being, such as the upper respiratory cells of a human, and uses the energy of those cells to make more copies of itself.
It steals it from its host. A virus enters the cells of the host animal and changes the cell's DNA/RNA to make it stop doing what it usually does for the host and start working on making copies of the virus using the host's resources and energy. A virus is not a living thing, so it must have a living thing work for it to make replications in a "reproductive" process. The reproductive process of the influenza viruses is the Lytic Cycle. See more about that in the related questions.
There is no such thing. viruses are so very small that a living thing could not live inside one. But a virus inside a living thing could be called latent if it is not causing a disease or active if it is.
Mostly No. A rhinovirus is a type of virus. A virus does not completely fit the accepted definition of a living entity.
no metabolism
