Best Answer

By fermentation, yeast (only some types) converts carbohydrates to carbon dioxide and alcohols.

In beer, the CO2 is captured to create foam, and the alcohol is self explanatory.

Once the alcohol level reaches a certain level, the yeast can no longer survive.

So a simple answer, is that years eat the carbohydrate of sugar, breathe out CO2, and alcohol is their excrement.
