Photosynthesis Quiz

What are autotrophs?

• Organisms that produce their own food

• Organisms that consume other organisms

• Organisms that do not require energy

• Organisms that can live without sunlight

What is the primary function of chloroplasts?

• To absorb sunlight

• To produce ATP

• To store energy

• To convert light energy into chemical energy

What do heterotrophs depend on for energy?

• Sunlight

• Autotrophs

• Inorganic substances

• Photosynthesis

What is the equation for photosynthesis?

• 6CO2 + 6H2O -> C6H12O6 + 6O2

• C6H12O6 + 6O2 -> 6CO2 + 6H2O

• 6O2 + 6H2O -> 6CO2 + C6H12O6

• 6CO2 + C6H12O6 -> 6O2 + 6H2O
