Question

How can viruses nourish themselves?

Answer 1

Viruses do not nourish themselves, it is because of this (and a few other reasons) that they are considered non-living.

Explanation:

Viruses are very simple particles that are able to do amazing things only due to the host's cell. A virus is made up of some DNA or RNA and a protein shell that is able to infiltrate a living cell.

Once the protein infiltrates the cell, the DNA or RNA is used along with the host cell's DNA and RNA to produce more of the virus.

Because it doesn't reproduce on its own and doesn't take in any form of energy to sustain itself viruses are considered non-living.
