Incorrect question, as crude oil contains elements that aren't in hydrocarbons. There is much more than carbon and hydrogen in crude oil. There is a long list of elements found in oil, and some of them don't occur in animals or plants. Also, there are elements found in animals and plants that don't occur in oil.
Go research the composition of crude oil compared to plants and animals for yourself. That's the only way you'll believe it, apparently.
Fluids, including hyrocarbons, in rock, assimilate various elements from the rocks they pass through and/or reside in. Does spring water contain elements that aren't in animals? (I don't know) Do animals contain elements not found in spring water? (again, I don't know) But the point I am making is that trace elements are not what hydrocarbons are made of.

I took organic chemistry and know full well what hydrocarbons are.
