Photosynthesis Plants us carbon to make their food and in return we get oxygen
Answer:
Photosynthesis
Explanation:
Plants remove carbon dioxide from the atmosphere through the photosynthesis process, returning only oxygen to the environment at the end of the process.
Photosynthesis is the process by which plants draw their food from light energy. In order for the plant to produce the energy necessary for its survival, it absorbs carbon dioxide and uses it to produce glucose, which is a carbohydrate used as a source of energy. All carbon dioxide that is not used in this conversion ends up being degraded by the plant.
