In the following question find out the alternative which will replace the question mark.

yeast : fermentation :: bacteria : ?

decomposition

The correct answer is OPTION 1 Decomposition

Here's why:

Yeast : fermentation describes a microorganism and the biological process it carries out. Yeast is responsible for the process of fermentation, where sugars are converted into alcohol and carbon dioxide.

Bacteria : decomposition similarly describes a microorganism and the biological process it carries out. Bacteria are responsible for the process of decomposition, where organic matter is broken down into simpler components.

Both pairs highlight the relationship between a microorganism and its characteristic biological function or process. Just as yeast is known for fermenting sugars, bacteria are known for decomposing organic matter.
