Photosynthesis is the process by which plants turn light energy into chemical energy. Plants also need carbon dioxide and water along with the light to complete the process.
The byproducts of photosynthesis are key to the survival of life on the planet. The carbon dioxide that the plants intake help clean the air and remove pollution. The plants release oxygen into the air as photosynthesis occurs, giving other organism the air they need to breathe. The sugars that the plant creates gives it energy and helps create carbohydrates in food producing plants. Carbohydrates are essential to those organisms that feed on these plants to fuel processes in their own bodies.
