Take a material living organism. Remove all the non-living hydrogen. Hydrogen is not living, so we have not removed life from the organism. Remove all the other non-living chemical elements in turn: helium, lithium, beryllium etc. All those chemical elements are non-living, so in all cases life was not removed from the organism. What is left after all the chemical elements have been removed is the life of the organism.
That is just one of the reasons why vitalism is incorrect. Life is an emergent property, it is not something separate from the components that make up the material organism.
