Explanation:

Viruses do not have the chemical machinery needed to survive on their own. Viruses seek out host cells in which they can multiply. Viruses can't be grown on synthetic media (e.g. agar [a type of geletin]) but they can be grown on cultures of bacteria. Bacteria reproduce and live like any other living organism would, it takes in nutrients and reproduces using binary fission (like mitosis).Viruses on the other hand are like little aliens. They really aren't "living" since they don't absorb nutrients or produce waste.
