Answer;
B) many fungi and bacteria
Step-by-step explanation;
-Fermentation is a metabolic process in which an organism converts a carbohydrate, such as starch or a sugar, into an alcohol or an acid. For example, yeast performs fermentation to obtain energy by converting sugar into alcohol.
-This metabolic process consumes sugar in the absence of oxygen. The products are organic acids, gases, or alcohol. It occurs in yeast and bacteria, and also in oxygen-starved muscle cells, as in the case of lactic acid fermentation. There are two types of fermentation: lactic acid fermentation and alcoholic fermentation.
