True or False: Calcium and phosphorus are examples of vitamins.

Calcium and phosphorus are classified as minerals, not vitamins. They play essential roles in various physiological functions within the body, including bone health, metabolic processes, and enzyme function. Vitamins, on the other hand, are organic compounds that are required in small quantities for a variety of biochemical functions.

The distinction between minerals and vitamins is important in nutrition and animal husbandry, as both are vital for growth and health, but they serve different roles in the body. Calcium, for example, is crucial for maintaining healthy bones and teeth, while phosphorus is important for energy production and cellular functions. Recognizing these definitions helps in understanding how to provide proper nutrition to livestock and the overall concept of animal health.
