Review the graphs carefully. Based on the information in Figures 2.5 and 2.6, explain the relationships between LED irradiance and carbon dioxide concentration over time for a chamber containing a water hyacinth. Use the evidence from the graphs and your knowledge of science to support your answer.

figure 2.5 shows the light intensity (LED irradiance) over time for a chamber containing a water hyacinth.

Figure 2.6 shows the change in carbon dioxide concentration over time for a chamber containing a water hyacinth.

According to the two graphs, increasing the LED irradiance caused a decrease in Co2 concentration in the chamber. This is evidence of photosynthesis by the hyacinth plant. By increasing the LED irradiance, the plant is able to make more carbohydrates using carbon dioxide in photosynthesis as shown in the formulae below the formulae;

6CO2 + 6H2O + (Sunlight energy)------> C6H12O6 + 6O2.
