bacteriophages are virus....the are not classified as living or non-living...well because..when they dont have a host (in this case Bacteria) they cannot reproduce which means they are non-living but when they are in a host (bacteria) they can reproduce and they do it at a very fast pace, in this case they are living....so you decide are they living or non-living?

I advise you to search the forum. You can find discussions about virus' being living or non-living.
A small hint for you. An organism can reproduce. Viruses can not do that themselves. They make their host do that.
