To match the biological terms with the corresponding numbers on the diagram, follow the typical photosynthesis and cellular respiration processes:
1: e. Chloroplast (the organelle where photosynthesis occurs) 2: h. Light energy (the energy source for photosynthesis) 3: b. Carbon dioxide (input for photosynthesis) 4: a. Water (another input for photosynthesis) 5: c. Glucose (the product of photosynthesis) 6: f. Mitochondrion (the organelle where cellular respiration occurs) 7: d. ATP (the energy currency produced in cellular respiration) 8: g. Oxygen (a byproduct of photosynthesis)
So, the final matches are: 1: e 2: h 3: b 4: a 5: c 6: f 7: d 8: g
Feel free to adjust if you have specific diagram labels; this answer is based on commonly accepted biology concepts.
