Is bread biotic or abiotic? Yeast is alive?

Bread is abiotic. Biotic means living or once lived. Abiotic means not living.

Yeast is alive. It is one-celled and a member of the fungus family, and when you add water to it and give it a little sugar for food, the organism "burps" and releases carbon dioxide-the gas that makes the bag puff out and makes sodas fizzy and bread fluffy.
