Q1) For primary producers such as plants, photosynthesis requires carbon dioxide (CO₂), water (H₂O), and sunlight. As a result of photosynthesis, plants produce glucose (C6H₁206) and oxygen (O₂). The CO₂ is used to make glucose. Energy from sunlight is used to power the reaction that creates the glucose molecules. The data set below is the results of a study that investigated how light intensity (distance from a light source; cm) affects photosynthesis (bubble production; #O₂ bubbles) in Elodea (aquatic plant).

Please identify the independent variable and the dependent variable in this study. B. Based on the data presented here, explain the trends you observed in the data (include average bubble production at each distance in your discussion). Additionally, conclude if you would accept or reject the hypothesis that light intensity does not affect photosynthetic activity and provide evidence to support your conclusion. C. Please produce a line or bar graph that supports your conclusion. Please be sure to properly label your graph.
