The diagram below shows the interrelationship between two processes.

Arrows pointing in the clockwise direction are shown along a circle. On top of the circle is the label Process A and moving clockwise we see an arrow, the label Oxygen and Glucose, another arrow, the label Process B, another arrow, the label Carbon dioxide and Water, and another arrow point back to Process A.

What do Process A and Process B most likely represent?

Both represent photosynthesis.
Both represent cellular respiration.
Process A represents cellular respiration and Process B represents photosynthesis.
Process A represents photosynthesis and Process B represents cellular respiration.

1 answer

Process A represents photosynthesis and Process B represents cellular respiration.

In this cycle, photosynthesis (Process A) uses carbon dioxide and water to produce glucose and oxygen, which are then consumed by cellular respiration (Process B) to produce carbon dioxide and water, completing the cycle.
