Which statement is supported by the data in the graph?
The rate of oxygen production is lowest in section M.
The rate of oxygen production is greatest in section M.
The production of water molecules is greatest in section L.
The number of carbon dioxide molecules in the beaker is greatest in section K.
Which statement explains the effect of temperature on the rate of photosynthesis?
Oxygen molecules break down at temperatures above 25 degrees Celsius.
The rate of photosynthesis is unaffected by the temperature of the water.

Why do leaves change color in the fall?
Chlorophyll goes into hibernation for the winter
Chlorophyll breaks down and accessory pigments can show through.
Accessory pigments break down and chlorophyll overpowers them
Accessory pigments go into hibernation for the winter
