[Serious] Why defecation?

[John 6IX Breezy]

This has been repeated a couple of times now in this thread, what exactly is stopping an omni-max deity from making a more efficient energy consumption system? Preferably one that doesn't involve ammonia.

I disagree that the system needs to be any more efficient. The complete removal of ammonia and other nitrogenous waste is detrimental to plant growth. We depend on plant growth; that's why it is a cycle.

I can't answer a question when I disagree with its premises; which are clearly dispelled off in an introductory textbook.
