What is the chemical formula for photosynthesis?

• 6CO2 + 6H2O + light energy -> C6H12O6 + 6O2

• C6H12O6 + 6O2 -> 6CO2 + 6H2O + energy

• H2O + CO2 -> H2CO3

• C6H12O6 + O2 -> CO2 + H2O + energy

The relationship between photosynthesis and cellular respiration is:

• Photosynthesis converts carbon dioxide and water into glucose and oxygen, while cellular respiration converts glucose and oxygen into carbon dioxide and water.

• Photosynthesis and cellular respiration are unrelated processes.

• Photosynthesis occurs in animals, while cellular respiration occurs in plants.

• Both processes produce energy in the form of ATP.

Which of the following best describes the net primary productivity of an ecosystem?

• Net primary productivity is the amount of energy captured by producers through photosynthesis over time.

• Net primary productivity is the amount of energy lost by producers through respiration over time.

• Net primary productivity is the amount of energy lost through respiration by producers subtracted from the gross primary productivity of an ecosystem.

• Net primary productivity is the amount of energy lost through respiration by producers added to the gross primary productivity of an ecosystem.
