Final answer:
Plants, yeast, and some microorganisms undergo the process of fermentation.
Step-by-step explanation:
Plants, yeast, and some microorganisms undergo a process known as fermentation. Fermentation is a metabolic pathway in which microorganisms convert sugars (carbohydrates) into alcohol, gases, and organic acids. Yeast, for example, is used in the fermentation process to produce bread, beer, and wine.
