A virus is a parasitic organism that attaches to a bacteria and multiplies by taking it's sustenance from the bacteria. It fulfills the basic definition of life to biologists: It has the ability to replicate itself. There is still debate over this, but most scientists believe viruses are living entities, though some describe them as being "at the edge of life". Vaccines to prevent infection by certain viruses fall into two types: live vaccine and dead vaccine. Vaccines are made from the virii themselves. Logically, you cannot make a live vaccine from a non-living thing. There is an even smaller, less understood relative of viruses called a "viroid", which is not well understood as of yet.
viruses do not grow, and viruses do not respond to changes in their environment. Therefore, viruses are not living organisms. All living things reproduce, but Viruses need living cells to reproduce because Viruses cannot reproduce by themselves.
Viruses can reproduce only inside a cell of living organisms. Viruses are sometimes considered non-living structures because they lack cells.
Viruses have some, but not all, of the characteristics of living things.
Yes **G1N4** I thought some living things are not organisms, because they are not free living.
One of the characteristics is they contain genetic material (DNA), which is a characteristic that all living things must have in order to be considered living. And also when inside a host, they are able to reproduce, which all living things must be able to do.
Viruses depend on living cells because they reproduce inside of them.

Yes. Viruses are living things too.
The difference is that viruses are smaller than bacteria. One more major difference is that bacteria are living things whereas viruses are non living things.
Viruses are not living things. Viruses are complicated assemblies of molecules, including proteins, nucleic acids, lipids, and carbohydrates, but on their own they can do nothing until they enter a living cell. Without cells, viruses would not be able to multiply. Therefore, viruses are not living things.

viruses do not grow, and viruses do not respond to changes in their environment. Therefore, viruses are not living organisms. All living things reproduce, but Viruses need living cells to reproduce because Viruses cannot reproduce by themselves.
Everything that are living are living organisms. Every other things are not considered to be a living organism e.g. viruses.
Bacteria and viruses are small and can only be seen through a microscope. The small living things are microorganisms or microbes. Some people do not think viruses are living things because they are acellular particles. They consider them to be an organic structure that interacts with living organisms.
Viruses are things that spread and contain germs. An Organism is a living thing.

They reproduce.
