Front

What is photosynthesis?

Back

A process where plants use CO2 and solar energy to produce oxygen (O2) and sugar.

Front

What is the chemical reaction for photosynthesis?

Back

6CO2 + 6H2O + solar energy → C6H12O6 (sugar) + 6O2

Front

What is respiration?

Back

A process where animals use oxygen to convert sugar into usable energy.

Front

What is the chemical reaction for respiration?

Back

C6H12O6 + 6O2 → 6CO2 + 6H2O + usable energy

Front

How are photosynthesis and respiration related?

Back

They are approximately the reverse of each other.

Front

What role does the atmosphere play in the water cycle?

Back

It holds water vapor and is where all weather occurs.
