Question

the process of _____ removes carbon dioxide from the atmosphere whereas _____ add carbon dioxide to the
condensation, precipitation
photosynthesis, cellular respiration
cellular respiration, photosynthesis
denitrification, nitrification

Explanation:

To solve this, we analyze each option:

• Condensation and precipitation are part of the water cycle, not carbon cycle, so first option is wrong.
• Photosynthesis uses \(\ce{CO_2}\) (removes from atmosphere), cellular respiration produces \(\ce{CO_2}\) (adds to atmosphere).
• Third option swaps these two, so wrong.
• Denitrification and nitrification are part of nitrogen cycle, not carbon cycle, so last option is wrong.

Answer:

B. photosynthesis, cellular respiration
