Define the term 'nutrition.'

The term 'nutrition' is best defined as the process of obtaining the food necessary for health and growth. This definition encompasses the entire process by which organisms take in food, metabolize it, and utilize the nutrients for various bodily functions such as energy production, tissue repair, and maintenance of overall health. Nutrition goes beyond mere consumption; it involves the assimilation of nutrients, their physiological impact, and the dietary choices that affect an individual's health.

While the study of chemical reactions in the body and how animals digest food are important aspects of biology and physiology, they do not fully capture the holistic nature of nutrition, which includes dietary habits and nutritional needs. Additionally, focusing solely on the consumption of vitamins does not represent the broader concept of nutrition, which involves a variety of nutrients including carbohydrates, proteins, fats, vitamins, and minerals that are essential for well-being. Hence, the correct definition reflects the comprehensive nature of how food contributes to health and growth.
