Micronutrients are essential elements
required by organisms in varying quantities throughout life to
orchestrate a range of physiological functions to maintain health.
Micronutrient requirements differ between organisms; for example,
humans and other animals require numerous vitamins and dietary
minerals, whereas plants require specific minerals. For human
nutrition, micronutrient requirements are in amounts generally less
than **0 milligrams per day, whereas macronutrients are required in
gram quantities daily.
