Question

why are viruses considered to non living forms sometimes ?justify?

Answer 1

First seen as poisons, then as life-forms, then biological chemicals, viruses today are thought of as being in a gray area between living andnonliving: they cannot replicate on their own but can do so in truly living cells and can also affect the behavior of their hosts profoundly.

Answer 2

viruses are considered non living sometimes because they are living when in the host cell and non living when outside the host cell.this means that they can do nothing when the are outside the body of living organism but may effect badly if they are inside the cell because it reproduce by using the energy of host cell.
