In a laboratory experiment, researchers investigated the effect of different concentrations of a nutrient solution on the photosynthesis rate of aquatic plants. The table below summarizes the experimental data collected over a two-week period:
Nutrient Concentration (mg/L) | Photosynthesis Rate (mg O2/g/hour) |
---|---|
50 | 1.5 |
100 | 2.3 |
150 | 2.7 |
200 | 2.8 |
Based on the data in the table, what was the photosynthesis rate at the highest concentration of nutrient solution?
