Do plants breath?
Yes! Plants breath in carbon dioxide from the atmosphere!

What is the carbon dioxide-oxygen cycle?
• The process that maintains Earth’s natural balance of carbon-dioxide and oxygen.

Why is the carbon dioxide-oxygen cycle so important?
• The cycle ensures that there is always carbon dioxide available for plants to make food.
• Plants, animals, and all other living things could not survive without one another.
• It ensures that there is oxygen for living things to break down food into energy.

The carbon dioxide-oxygen cycle is very complex.
A forest fire uses oxygen and releases carbon dioxide into the air.

When we burn fossil fuels, we release into the atmosphere carbon that was stored by living things millions of years ago.

What is photosynthesis?
• The process by which organisms use energy from the sun to make their own food.
• Simple sugars, such as glucose, are the food that is made.
• These sugars contain carbon from the carbon dioxide-oxygen cycle.
