To match the letters in Column A with the inputs and outputs of photosynthesis in Column B, we can identify the following associations based on the process of photosynthesis:
- A: d. Carbon Dioxide (Input)
- B: b. Water (Input)
- C: c. Glucose (Output)
- D: a. Oxygen (Output)
So the matching is as follows:
- A: D (Carbon Dioxide)
- B: B (Water)
- C: C (Glucose)
- D: A (Oxygen)
