We discussed chemical reactions in our last unit. When producers take water and carbon dioxide to make food using energy from sunlight, they are turning substances into a new substance. This means this is a chemical reaction that occurs in the producers!

We call this chemical reaction photosynthesis!

The chemical reaction of photosynthesis also produces oxygen which helps us humans stay alive!

Photosynthesis: Starting Substances

What Matter do you start with?

2

Photosynthesis: End/Product Substances

What Matter do you end up with?

Photosynthesis

6CO2 + 6H2O + (energy) → C6H12O6 + 6O2
Carbon dioxide + water + light → glucose (sugar) + oxygen
