What viruses do is they are not living, so they use the cell's life to 'reproduce'. They take all of the cell's nutrition and use that to multiply. Then the cell is dead, and the viruses go on to take over more cells.
Most scientists consider viruses as the link between living an non living organisms. Viruses are considered non-living by some scientists because - 1) They donot perform any metabolic activities. 2) Outside the host cell , viruses are present only in crystalised form. (Even after it is un-crystalised , it does not lose it's capacity for infection) 3) It does not require any sort of "food".
Biologists consider viruses to be non-living because they lack the cellular structure and metabolic processes characteristic of living organisms. Viruses cannot reproduce independently; they require a host cell to replicate and carry out their life cycle. Additionally, they do not exhibit growth, respond to stimuli, or maintain homeostasis, which are key features of life. As a result, viruses are often classified as complex molecules or biological entities rather than living organisms.
No. Virologists, the scientists who study viruses, don't consider them living things because they do not meet all the criteria of the definition of life.
Well, honey, scientists don't believe viruses are living organisms because they lack the ability to carry out essential life processes on their own. They can't reproduce without hijacking a host cell, so they're more like freeloaders than independent living beings. It's like calling a computer virus a living thing just because it can mess up your day.
Many, if not most biologists do not consider viruses living. So, they are not on any phylogenetic tree that I know of. They may have a phylogeny that I am unaware of, though.
They don't have a Nucleus.

Viruses either have a strand of DNA or RNA not both like living organisms. They need a host (you and me) in order to replicate.

None. Viruses are acellular. Many biologists do not consider viruses to be living things in part because they are acellular. Look at any phylogeny (tree of life). Viruses are not on them.
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.
A scientist that studies viruses is called a virologist.
Biologists consider dormant virions to be non-living because they must obtain a host to function and replicate themselves. However, active viruses are considered to be living, by most scientists.

Virology is the study of viruses and their evolution, structure, classification. It also is complexes of nuclies acids and proteins that help all living cells.
