In the context of nutrition, a mineral is a chemical element. Some "minerals" are essential for life, but most are not. [ 1 ] [ 2 ] [ 3 ] Minerals are one of the four groups of essential nutrients; the others are vitamins , essential fatty acids , and essential amino acids . [ 4 ]
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).
Plant nutrition is the study of the chemical elements and compounds necessary for plant growth and reproduction, plant metabolism and their external supply. In its absence the plant is unable to complete a normal life cycle, or that the element is part of some essential plant constituent or metabolite .
Nutrition is the biochemical and physiological process by which an organism uses food to support its life. It provides organisms with nutrients , which can be metabolized to create energy and chemical structures.
Minerals (e.g., salts) and organic substances (e.g., vitamins) can also be found in food. [4] Plants, algae , and some microorganisms use photosynthesis to make some of their own nutrients. [ 5 ] Water is found in many foods and has been defined as food by itself. [ 6 ]
Fossil skeletal parts from extinct belemnite cephalopods of the Jurassic – these contain mineralized calcite and aragonite.. Biomineralization, also written biomineralisation, is the process by which living organisms produce minerals, [a] often resulting in hardened or stiffened mineralized tissues.
Plants tend not to use vitamins, although minerals are required. [8] [21] Structure of the Mn 4 O 5 Ca core of the oxygen-evolving site in plants, illustrating one of many roles of the trace mineral, manganese. [22] Some seven trace elements are essential to plant growth, although often in trace quantities. [citation needed]
