Yes but I suppose life by its simplest definition could also be described as an effect from a reaction, rather than a thing, making the living object (the thing) simply a vessel for the reaction. So I suppose the whole fire system would be “the thing” in this scenario.
MRS GREEN would still exclude viruses as being alive. As viruses can neither respirate nor reproduce without a host cell and they can also not grow.
I’m weird and think a virus in a system of virus + host cell, is a part of the living cell, even if its a detrimental self-serving part.
