Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What do all living organisms use to release energy stored in food?
A
digestion of food molecules into oxygen that then creates a energy called molecular gases
B
aerobic respiration and anaerobic respiration
Explanation: 

Detailed explanation-1: -The food has stored energy, which is released during respiration. Therefore, all living organisms respire to get energy from food. During breathing, we breathe in air.

Detailed explanation-2: -Facultative anaerobes are organisms that can switch between aerobic and anaerobic cellular respiration processes, like some bacteria and yeasts.

Detailed explanation-3: -Carbon dioxide and water are created as byproducts. The overall equation for aerobic cellular respiration is: In cellular respiration, glucose and oxygen react to form ATP. Water and carbon dioxide are released as byproducts.

Detailed explanation-4: -Answer: Solution: The energy released during respiration is used for carrying out various life processes. Some of the energy liberated during the breakdown of the glucose molecule is in the form of heat, but a large part of it is converted into chemical energy released by these ATP molecules.

Detailed explanation-5: -Thus, the correct answer is “Oxygen” is used for respiration in living organisms which reacts with foods and releases energy. NOTE : The organism which obtains energy with the use of oxygen is referred to as aerobes. The organism that obtains energy without the use of energy is referred to as Anaerobes.
