Nutrients are substances that the body needs to carry out its various functions, such as energy production, tissue repair, and immune system function.

In summary, nutrition is necessary for an organism to maintain its health, growth, and development. A balanced and varied diet that provides all the necessary nutrients is essential for optimal health and well-being.
