Photosynthesis (option A) is the process by which plants convert sunlight into energy. Cellular respiration (option B) is the process of converting glucose into ATP for energy production. Cell division (option C) is the process by which a cell divides into two daughter cells. Therefore, phagocytosis is the most relevant process that breaks down cellular components for recycling or waste removal.
