Answer:
B) all living organisms carry out some form of respiration.
Explanation:
Respiration is an oxidative process which takes place in all living cells and it takes place all the time whether is day or night. In this process, the respiratory substrate such as glucose is oxidised to produce carbon dioxide, water and energy (ATP). The oxidation of substrate may be oxidised aerobically or anaerobically. It begins and completes in the cytoplasm in case of anaerobic respiration but in case of aerobic respiration, it begins in the cytoplasm and gets completed in the mitochondria.
