Modes of Nutrition

It is a biological process of providing or obtaining food that is necessary for growth and health. It includes many physiological processes - absorption, ingestion, assimilation, catabolism, excretion, etc. In biology, the science that deals with nutrition's physiological and chemical processes are called "nutritional science."
