Explanation:
A sugar is a source of carbohydrate which is made up of carbon and oxygen atoms. Providing a yeast with more amount of sugar will increase the process of fermentation which is the anaerobic respiration. The carbon dioxide will be released after this process. The released carbon dioxide gas can be measured by observing the shape of the balloon and measuring the quantity of carbon dioxide present in the balloon.
