Viruses are considered non-living because they cannot carry out essential life processes on their own, such as metabolizing nutrients or replicating. They require a host cell to replicate and do not have the ability to grow or respond to stimuli independently.
viruses, in the first place, are non living. when they enter a substrate (e.g. host), that's the time they exhibit actions and processes pertaining to a living organism. this is also the reason why putting viruses in the classification system is still on debate.
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 lack the cellular structure and independent metabolism typically found in living organisms. They can only replicate inside a host cell by hijacking the cell's machinery. This unique mode of reproduction blurs the line between living and non-living entities, making viruses challenging to classify definitively.
viruses are not considered to be living organisms as they lack the cellular structure and cannot carry out cellular functions on their own. They can only replicate by hijacking the machinery of living cells. Therefore, viruses do not challenge the concept that all living things are made of cells.
Viruses are particles that reproduce by infecting living cells. They consist of nucleic acids, proteins, and sometimes lipids.
They arent alive
viruses are non living and bacteria are living organisms
Viruses are not classified into any of the kingdoms because they cannot live outside of a host cell (they depend on the host cell's DNA to reproduce and undergo metabolic reactions within it).
There actually living
no there arent
Viruses depend on living cells because they reproduce inside of them.
Viruses need living cells to produce more viruses. They are obliged to use living cells.
If I had to pick one, I'd say heterotrophic, but really they're not any of the above. Autotrophic (which includes hemosynthetic) and heterotrophic describe where a living thing gets its energy. Viruses aren't really living things. Also, they don't produce their own energy. Let's take poliovirus as an example. It consists of genetic material (RNA) inside a capside (a shell made of protein). It just floats until it binds to a receptor, gets taken up by a cell, and releases its RNA into the cell. All of this is done with the cell's energy. Then it uses the cell's supplies of molecules, machinery, and energy to replicate, making more copies of itself. It never actually produces ATP energy.
Viruses require a living organism to do anything - most especially to reproduce.

Many are.
