The ontological difference distinguishes specific entities from the Being they have.

Evidence

For without consciousness, Being does not exist either as a totality (in the sense of “the world,” “the universe”) or with differentiated parts. It is a fullness of existence, a plenitude which can not possibly isolate one part so as to contrast it with another, or posit a whole over against its parts, or conceive a “nothing” in opposition to which it is “everything.” It is simply undifferentiated, meaningless massivity. Without consciousness there would not be a world, mountains, rivers, tables, chairs, etc.; there would be only Being. In this sense there is no thing without consciousness, but there is not nothing. Consciousness causes there to be things because it is itself nothing. Only through consciousness is there differentiation, meaning, and plurality for Being. — Jean-Paul Sartre, Being and Nothingness, 40 (#expands, via linked claim)
