Q1а: Fоr primаry prоducers such аs plants, phоtosynthesis requires carbon dioxide (CO2), water (H2O), and sunlight. As a result of photosynthesis, plants produce glucose (C6H12O6) 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). # of bubbles produced @ 5 cm # of bubbles produced @ 10 cm # of bubbles produced @ 20 cm # of bubbles produced @ 30 cm Group 1 0 9 7 0 Group 2 2 12 6 3 Group 3 2 9 9 2 Group 4 0 8 10 0 Group 5 1 10 7 5 Group 6 3 13 4 4 Group 7 3 10 8 4 Please identify the independent variable and the dependent variable in this study.
