each other.

They lost money on every deal, but they made it up in volume?

No, seriously, they had to have some source of energy and carbon. There
are many possibilities, some of which are still working today. There are
many inorganic processes that make high-energy molecules, some of whose
energy can be extracted. Currently living bacteria make use of all of
them. Look up, for example, "chemautotroph".

Original organisms probably evolved as a community that was overall autotrophic. It is speculated (for we cannot know for sure) that they worked off volcanic flows containing H2S, but I am betting that they would happily reuse each other's high entropy molecules as well if they could.
