In the context of the carbon cycle, the correct options are:
b. Cellular respiration releases carbon dioxide into the atmosphere
c. Photosynthesis captures carbon dioxide from the atmosphere
Explanation:
- Photosynthesis occurs in plants, algae, and some bacteria, where they capture carbon dioxide (CO2) from the atmosphere and convert it into glucose and oxygen, thus removing CO2 from the atmosphere.
- Cellular respiration occurs in living organisms, where glucose is broken down into energy, and as a byproduct, carbon dioxide is released back into the atmosphere.
Option a is incorrect because photosynthesis does not release CO2; it uses it. Option d is also incorrect because cellular respiration does not capture CO2; it releases it.
