Here's how it works:
1. Plants and algae use sunlight, water, and carbon dioxide to create their own food (glucose) and release oxygen as a byproduct.
2. Sunlight provides the energy for the reaction.
3. Water is absorbed from the soil or water.
4. Carbon dioxide is taken in from the air.
5. Glucose is used for the plant's growth and energy.
6. Oxygen is released into the atmosphere.
This process is essential for life on Earth, as it provides the oxygen that all animals, including humans, need to breathe.
