This is a bit of an odd question, but here goes.
Your body needs energy to function. Each organ (brain, heart, etc.) need different amounts of energy to function properly. So it stands to reason that your heart's minimum required energy is higher than that of your spleen (just an example). So here's my question:
"Which organ requires the most minimum energy, and how much energy is the minimum?"
I'm asking this question because I'm trying to figure out "if energy were removed from a body, such that all parts of the body had the exact same amount of energy, what would be the minimum energy needed to make sure no organs failed" (this has to do with World Building, to an extent).
Furthermore, it'd be very helpful to know how much energy would be required for said organ not only for survival, but also to maintain a relatively normal, or even active, functionality. Would this equal the energy normally found in a person, or could it be lower?
If I need to clarify further, just let me know. Thank you in advance!
