Autotrophic cells produce their own energy.

Autotrophgenesis is the ability of a DNA Alternate to be completely self-sustaining. Taking its name from autotrophic cells (cells that are 100% self-sustaining), Autotrophgenesis is the biological adaptation, aided by evolution, that allows the body to be completely self-reliant. The Alternate would no longer need to process air for oxygen or ingest sustenance (food or water). The normal system of organs could become inactive as there would be no need for them to function, but they are still fully functional and are capable of use at any time. This ability frees the Alternate from ever having to breathe, sleep, eat or drink ever again. This also bring speculation as to whether or not the Alternate could survive what would normally be a fatal wound for a human (such as drowning in blood due to pierced lungs).
