After reading the recently-revived question about are Terminators cyborgs something occurred to me. If the flesh covering a Terminator is "real", as in living and indistinguishable from actual human flesh, it needs to be fed in some way. See the characteristics of life.
The question mentions that only the terminator from the TV show has ever been shown to eat, so how does the flesh stay alive if it's not getting nutrients somehow? Has this been addressed in the series somewhere? Does the endoskeleton have a nutrient pack or something?
This somewhat connects to the original question in that if the flesh has been altered in some way to not need nutrients and at the same time not die, then you could argue that it's not "real" human/living flesh, which would then put the definition of "cyborg" under question. But I thought it warranted a separate question.
