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

Here's what each part represents:

* 6CO₂: Six molecules of carbon dioxide

* 6H₂O: Six molecules of water

* light energy: Energy from sunlight

* C₆H₁₂O₆: One molecule of glucose (a simple sugar)

* 6O₂: Six molecules of oxygen

In words, the equation means:

Carbon dioxide and water, in the presence of light energy, are converted into glucose and oxygen.

This process occurs in plants, algae, and some bacteria. They use the energy from sunlight to convert carbon dioxide and water into glucose, which they use for food, and oxygen, which is released into the atmosphere.
