In the virtual experiment done, how will you describe the graph shown when there is an increasing rate of light intensity and high concentration of carbon dioxide?

• There is an icreased rate of photosynthesis as the light intensity increases as shown in the graph

• There is a decreased rate of photosynthesis as the light intensity increases as shown in the graph

• There is a decreased rate of photosynthesis as the light intensity decreases as shown in the graph

• There are no changes in the rate of photosynthesis as shown in the graph
