1 is irrelevant to autotrophs (e.g. cyanobacteria), who can synthesize their own food from achiral CO2 using sunlight; 2 is pretty much guaranteed if it’s the only mirror life form in the ecosystem; 3 is obvious if it’s the mirror image of an already existing life form; and it doesn’t have to do 4 and 5 to achieve 6 (even a mirror cyanobacterium not otherwise interacting with non-mirror life would keep replicating and replicating exponentially until the biosphere runs out of CO2 or whichever other achiral nutrient turns out to be the limiting factor)
