Answer:The answer is B: Cellular respiration
Step-by-step explanation:
Living things get energy from a process called cellular respiration. This process occurs in the cell's mitochondria. During cellular respiration, the mitochondria use oxygen to break down glucose (basically sugar found in food) to create a form of energy called ATP. In addition, the cell produces carbon dioxide and water, which are released as waste. Feeling sluggish? Need a boost of energy? Go ahead and feed your mitochondria. It will help keep your energy levels in balance!
