    Importance of Photosynthesis and Respiration Explain how photosynthesis and respiration are linked in order to provide you with energy from the food you eat: Photosynthesis is the process in which certain life forms are able to use sunlight to create energy. This energy is created by making carbohydrates from carbon dioxide and water in the presence of chlorophyll. Plants release large amounts of oxygen into the atmosphere as they produce much more than needed during the photosynthesis process.
