Yes, even bacteria from u/FrostReaver 's answer is a parasite. Most organisms need something that was made by some other organisms. We divide life into things but because it's easier to analyze it that way, but they both depend on each other and influence each other (the same relationship as within parts of an organism).

So I wonder, is there any organism that if we put on say mars, it could function without any ecosystem? By function I mean not only survive but exponentially reproduce given available resources there. A follow up question would be if it would just deplete the resource it was feeding o and die after that, or could it bootstrap a whole ecosystem (theoretically, after many many millions of years).
