What's the difference between organogen and sulphur?
Organogen
Definition:
(n.) A name given to any one of the four elements, carbon, hydrogen, oxygen, and nitrogen, which are especially characteristic ingredients of organic compounds; also, by extension, to other elements sometimes found in the same connection; as sulphur, phosphorus, etc.

Sulphur
Definition:
(n.)
