A temperature which is too high would be able to produce little to no oxygen because of the extreme temperature. Just like a temperature too high‚ a temperature which is too low would also produce little to no oxygen for the same reason. Animals that have livers are considered warm-blooded‚ with very warm temperatures; therefore it would make sense for a warm temperature to produce the most oxygen; but one
