Question 8 • SC332 Environmental Science B

Both photosynthesis and cellular respiration are part of the carbon cycle. Which statement best compares these two processes?

Answer
A
Both release carbon dioxide as waste.
B
Both provide organisms with usable energy.
C
Both add bacteria to the soil.
D
Both require fixation in order to convert molecules.

Explanation

Photosynthesis stores energy from sunlight in glucose, while cellular respiration releases usable energy from glucose for cells. So both processes are connected to providing usable energy, although they do so in different ways. Photosynthesis takes in carbon dioxide, and respiration releases it, so choice A is not correct.
