Is it possible for any introduced extremophiles to actually survive and reproduce without a biosphere to sustain them? My understanding is that all life on earth depends on some other life’s metabolic processes for something, be it food, amino acids, or something else. Can a single species that evolved in such a complex ecosystem possibly sustain itself alone on a planet so unlike it’s origin?
