Photosynthesis is the process plants use to convert sunlight into chemical energy. the process of photosynthesis can be modeled to illustrate the most important aspects of the natural phenomenon. through this process, plants use energy in sunlight to turn carbon dioxide gas and water into sugar. plants then use this sugar to grow. at the same time, plants produce oxygen gas as a waste product which animals breathe. a)limiting water will limit sugar production of the plantb)limiting sunlight will limit sugar production of the plantc)limiting carbon dioxide will limit sugar production of the plantd)limiting sunlight, water, or carbon dioxide will limit sugar production of the plant
