They don't have their own metabolism and they can't reproduce on their own, two reasons for which they are obligatory parasites. They have to infect other cells with metabolisms to reproduce.
because they travel around the earth in gases form in the air
When they are inside other living things and the other one I have no idea
The only characteristic of a living thing that is shared by viruses is genetic material, either DNA or RNA. They do not reproduce, their genetic information hijacks a living cell's machinery, and turns the cell into a virus factory, this is called replication. They do not require food. Some viruses have moving parts that allow them to inject their genetic material into the host cell.
you can classify them by: non- living things what they eat
itcan be spread from the air we breathe ... and also things we touch.
Growth depends upon ingestion, so let's start with two ways living things eat: autotrophic (self feeding) and heterotrophic (needs to find food).

Viruses are living things, but very strange: they barely make the list of life.1. Viruses do not eat or give off waste.2. Viruses do not grow.3. Viruses cannot reproduce on their own: they have to hijack cells since they don't have the equipment themselves.4. Viruses are a whole lot smaller than even bacteria: an influenza virus is ten times shorter than a Strepoccocus bacterium that causes strep throat.
They do not do what we (or even bacteria do): 1. grow on their own 2. respire 3. take in nutrients 4. reproduce 5. respond to their enviroment

There are many ways that viruses are NOT like living organisms. Viruses differ from living organisms in the following ways: • Viruses cannot reproduce without the help of a host cell • Viruses do not metabolize organic nutrients, but instead use ATP made by the host cell. • Viruses are not separated from their external environment by some sort of barrier like a cell wall or membrane. • Viruses contain either DNA or RNA but never both. A virus can also be like organisms in that they still consist of macromolecules like proteins, nucleic acids, carbohydrates and lipids just like organisms do.

1) Viruses do not grow, they are a certain size from the moment they are made. Just a protein coat and a set of genetic instructions. 2) Viruses do not respire they don't turn over energy at all, they hijack living cells which can turn over energy and use them to do their reproduction. 3) Viruses do not excreat waste products- they don't make any so they don't need to. Most living things make some toxic substances which must be got rid off eg carbon dioxide and urea. 4) Viruses cannot reproduce, make more of their own kind without hijacking the apparatus of a living cell.
Living things have cells. And living things use energy.

By various ways like by sending viruses.
Different living things excrete in different ways: there is no single way.
