Viruses are not an organism at all. They are nonliving. They are like cockle burrs that "grab" hold of your clothing or a dog's coat. They are hijackers. Once they get attached to the cell of a living cell, they can take it over and "make" the living cell produce virus particles instead of cell parts. These particles can assemble into more viruses and then they break out of the cell (killing it) and begin the process again. They cannot make more viruses on their own.

Viruses do not have complex membranes like eukaryotic organisms have. Viruses also do not have cells, nor are they technically living organisms. There is no need for viruses to control the movement of material in and out of the viral particles.
Bacteria are able to reproduce on their own while viruses need a host to "hijack" so they can reproduce. Bacteria have metabolisms, catabolic and anabolic biochemical reactions going on in their cells all the time. Viruses do not. Bacteria can grow in size to a certain extent while viruses do not change in this regard. The definition of living things classify bacteria as a living thing, while viruses are not.
viruses are non living and bacteria are living organisms
VIruses can only reproduce. They can not respire, excrete, nutrition, grow, they don't have sensetivity either. Remember: viruses still are living things because they have genes in them.:) hope it helped. thanks! :P
Many scientists consider viruses to be non living because each and every living organism must carry out these 7 life processes for it to be considered living: Movement, Reproduction, Sensitivity, Growth, Respiration, Excretion and Nutrition. Viruses do all of these things except reproduction, which they cannot do. Instead, they multiply by using other living organism's cells which has caused a lot of debate over whether that counts as reproduction in the scientific community.
There actually living
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.
Viruses are not considered living organisms because they cannot carry out basic functions without a host cell. They lack the ability to replicate on their own and do not have cellular structures like other living organisms.
Viruses require a living organism to do anything - most especially to reproduce.
