Explanation:

Most viruses need a living host organism-they are more like a parasite. Viruses reproduce by sticking their DNA into living cells and their DNA "takes over" the living cell and uses the living cells' tools to replicate the virus' DNA and make more viruses. Bacteria and Fungi are used in decomposition and need the dead animals' flesh for food.
