Answer:
B. sugar + oxygen → carbon dioxide + water + energy
Explanation:
Energy is that which sustains living organisms, so as to perform various activities. One of the processes by which living organisms produce energy is by respiration.
Respiration involves the breathing-in of oxygen and breathing-out of carbon dioxide as a waste. The oxygen helps in breaking down molecules of carbohydrates e.g sugar in the system of living organisms into energy, carbon dioxide and water.
This process is well represented by the equation in option B.
