Question

which of the following diagrams represents the correct cycling

Explanation:

Photosynthesis uses \( CO_2 \) and produces \( O_2 \); respiration uses \( O_2 \) and produces \( CO_2 \). Diagram B shows Photosynthesis releasing \( O_2 \) (used by Respiration) and Respiration releasing \( CO_2 \) (used by Photosynthesis), matching the cycle.

Answer:

B. Diagram B (with Photosynthesis releasing \( O_2 \) and Respiration releasing \( CO_2 \), forming the correct cycle)
