[DC]Does Superman need to urinate or defecate?

First off, why does he like pie? He doesn't even need to eat or drink.  
  
So if he does eat food, does he urinate or defecate?
gpt
He doesn't need to eat if he is exposed to yellow sun light but he can if he wants to.

Superman had a normal upbringing by loving parents with traditional values, meals with the whole family is an important part of that so he definitely sees the social value in eating and enjoys the taste.

And as we all know if you eat you have to poop.
