Answer 2

Answer:

Water added

Explanation:

The above option is the best that represents the missing step.

This process is known simply to be cellular respiration. It is also the reverse of photosynthesis.

In this process, food is broken down in a chemical reaction with oxygen. As this process occurs, carbon dioxide and water are the products. So, in this process, water is added as the product of the breaking down process.

Respiration is seen to be almost the exact opposite of photosynthesis. These two reactions help to maintain biological energy balance on earth.
