Produce+waste+HN

When a living thing produces waste it is usually the waste it doesn't need. It gets rid of the waste because the waste might cause damage in the body. This is also called excretion. Eg. Feces(poop), flatulent(fart), urine(pee), vomit, carbon dioxide, old/dead cells, mucus(snot/boogers), saliva(spit).

Some animals/plants eat other animals or plants wastes for example: A fungus called Yeast absorbs sugar as an energy source and makes alcohol.
