Micronutrients are nutrients such as vitamins and minerals required by organisms in varying quantities throughout life to orchestrate a range of physiological functions to maintain health. [1] [2] The following is a list of micronutrients used by various living organisms. For human-specific nutrients, see Mineral (nutrient).
A heterotroph (/ ˈ h ɛ t ər ə ˌ t r oʊ f,-ˌ t r ɒ f /; [1] [2] from Ancient Greek ἕτερος (héteros) 'other' and τροφή (trophḗ) 'nutrition') is an organism that cannot produce its own food, instead taking nutrition from other sources of organic carbon, mainly plant or animal matter.

A nutrient is a substance used by an organism to survive, grow and reproduce. The requirement for dietary nutrient intake applies to animals, plants, fungi and protists.

Granulated sugar provides energy in the form of calories, but has no other nutritional value. In human nutrition, empty calories are those calories found in foods and beverages (including alcohol) [1] composed primarily or solely of calorie-rich macronutrients such as sugars and fats, but little or no micronutrients, fibre, or protein.
Water makes up a large proportion of the total mass ingested as part of a normal diet but it does not provide any nutritional value. Ethanol provides calories but there is no requirement for ethanol as an essential nutrient. Even though macros and calories are different concepts, they are dependent on each other.
