The diagram shows the famous Engelmann experiment that helped us understand important aspects of the process of photosynthesis. What conclusion can be drawn by the pattern of accumulation of aerobic bacteria shown in the diagram?
| 1. | Excess carbon dioxide is released by the alga in the area of accumulation. |
| 2. | Only red and violet lights are effective for photosynthesis. |
| 3. | In the areas of accumulation, most oxygen was liberated by the alga. |
| 4. | Bacteria are attracted to red and blue light. |
