(2) water is produced.

(3) energy is released.

• (3) only

• (1) and (2) only

• (2) and (3) only

• (1), (2) and (3)

Which of the following chemical equations correctly represents the process of respiration?

• 6H₂O + 6CO₂ → C₆H₁₂O₆ + 6O₂

• 6H₂O + 6O₂ → C₆H₁₂O₆ + 6CO₂

• C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O

• C₆H₁₂O₆ + 6CO₂ → 6O₂ + 6H₂O

Jason prepares the set-up and leaves it for one hour.

After one hour, the hydrogencarbonate becomes yellow. This observation shows that

• carbon dioxide is produced by the mealworms in respiration.

• carbon dioxide is used by the mealworms in respiration.

• oxygen is produced by the mealworms in respiration.

• oxygen is used by the mealworms in respiration.
