Respiration is a process by which living organisms convert nutrients into energy, releasing waste products in the process.
The products of respiration are carbon dioxide and water. During respiration, glucose (or other energy-rich molecules) is broken down in the presence of oxygen to release energy. This process is called aerobic respiration. The byproducts of this process are carbon dioxide and water.
Carbon dioxide is a gas that is produced when the carbon atoms in glucose are oxidized, while water is formed from the hydrogen atoms in glucose combining with oxygen. These waste products are then eliminated from the body through exhalation (carbon dioxide) and urination (water).
Therefore, the correct answer is "carbon dioxide and water" are the products of respiration.
