What is the formula for photosynthesis as mentioned in the document?

• CO2 + H2O + sunlight ---> C6H12O6 + O2

• CO2 + O2 + sunlight ---> C6H12O6 + H2O

• H2O + O2 + sunlight ---> CO2 + C6H12O6

• C6H12O6 + O2 ---> CO2 + H2O + sunlight

Where does the carbon dioxide used in photosynthesis mainly come from?

• From the soil through the plant's roots

• From living organisms that exhale it and from factory smokestacks and car fumes

• From water molecules in the ground

• From the sunlight absorbed by the chloroplasts

Why are plants considered autotrophs?

• Because they require food from other organisms.

• Because they can make their own food using photosynthesis.

• Because they produce carbon dioxide and water.

• Because they consume glucose and oxygen.
