One of the best perks of being a higher ranked creature was the autonomy of one's body from many natural necessities. The need for nutrition could be greatly simplified and shortened compared to multiple meals every day. One could just store a lot of nutrition in their body in one go and not eat for weeks. Similarly, they didn't really have to urinate or defecate. The body's digestive system, regardless of the creature's lifeform, could fully utilize every bit of the food to fuel the cells.
