Why is cellular respiration necessary for all organisms?

• It releases useful chemical energy for cell functions.

• It expels harmful carbon dioxide from the lungs of all organisms.

• It brings oxygen into the body, avoiding suffocation.

• It produces glucose for all cells to use.

How do photosynthesis and cellular respiration demonstrate the law of conservation of mass?

• Sunlight is converted into sugar, converting energy into mass.

• The carbon in photosynthesis converts into oxygen for respiration.

• The amount of energy absorbed from the sun equals the amount of energy stored in sugar.

• The atoms involved in the reactions get recycled.
