Answer
Respiration.
Explanation
The question pertains to fundamental biological concepts concerning cells and the processes they undergo. Cells use a process called respiration to release energy from food substances (specifically glucose). The process of respiration includes steps like Glycolysis, the Krebs cycle, and the Electron Transport Chain, which occur in the presence or absence of oxygen. Essentially, during respiration, cells break down glucose and create adenosine triphosphate (ATP), a type of energy currency that the cell's metabolic processes use. In contrast, Digestion is a process where food is broken down into simpler nutrients in the stomach and intestines; it's not a process occurring at the cellular level. Excretion is a process by which waste products are removed from the body, and Burning typically refers to a chemical reaction that produces heat, light, and new substances; it is not a process that the body uses to extract energy from food. Hence, these are not the accurate terms we are looking for.
