In an experiment to see if fertilizer works on a cactus, students have two cacti. Both cacti receive the same water and sunlight. Both cacti are in the same place within the room, and the temperature is the same for both cacti. However, one cactus gets fertilizer and the other does not. Identify the independent
variable and the dependent variable.
A. The independent variable is the sunlight. The dependent variable is the fertilizer.
B. The independent variable is the fertilizer. The dependent variable is the growth of the cacti in centimeters.
C. The independent variable is the cactus that did not get fertilizer. The dependent variable is the sun.
D. The independent variable is the fertilizer. The dependent variable is the sun.
B. The independent variable is the fertilizer. The dependent variable is the growth of the cacti in centimeters.
