Where does your body get the carbon it needs to build organic molecules?

Your body obtains carbon primarily from the food you consume, which contains organic molecules like carbohydrates, fats, and proteins. When you digest these foods, the carbon atoms are released and then used to build new organic molecules necessary for growth, repair, and energy. Additionally, carbon dioxide from the air is also utilized by the body during processes like respiration, contributing to metabolic functions. Overall, dietary intake is the primary source of carbon for organic molecule synthesis.
