<span>Viruses are regarded as being on the borderline of living and non-living because it exhibits characteristics of both living and non-living organisms. Inside a host, the virus can act as a living organism using the host's cellular system while outside the host, the virus crystallizes that makes them incapable of conducting metabolic activities. </span>
<span>Three fossil fuels are, natural gas, coal and oil
I guess what could differentiate them is that: </span>Coal is a solid fossil fuel formed over millions of years by decay of land vegetation. When layers are compacted and heated over time, deposits are turned into coal. Whereas Oil is a liquid fossil fuel that is formed from the remains of marine microorganisms deposited on the sea floor and gas like oil, it is formed from the remains of marine microorganisms.<span>
So the difference could be how they are formed</span>
