Answer 6

Ammonia and bleach are the waste products of my brain cells slowly dying. All animal cells release carbon dioxide. Oxygen is not a waste product, it is what we take in. Urine is not a cell product and hydrogen are building blocks of life.

The Carbon Cycle is an important part for human evolution.
