What happens to the C6H12O6 when it is eaten by elk

There are no options but the answer can be provided based on general understanding. The answer is:

It is used to synthesize energy (ATP)

Explanation:

C6H12O6 is the chemical formula for glucose molecule, which is a simple sugar or monosaccharide. It is the simplest unit of carbohydrate molecules. Glucose is a precursor of cellular energy i.e. ATP in living systems. When food is eaten by an organism such as elf, it gets broken down or digested to a simpler unit, which is usually glucose.

This glucose is then absorbed by the cells of the organism, where the stored energy in its bonds is converted to a usable energy by the cell, called Adenosine triphosphate (ATP) in a process called CELLULAR RESPIRATION. Hence, the C6H12O6 (glucose), when eaten by an organism such as an elk, is used as a source of energy to the cell.

a. decomposes use carbon from dead organisms as fuel for cellular respiration, returning carbon dioxide back into the atmosphere.
