In the context of nutrition, a<unk> is a chemical element required as an essential nutrient by organisms to perform functions necessary for life. However, the four major structural elements in the human body by weight (oxygen, hydrogen, carbon, and nitrogen), are usually not included in lists of major nutrient<unk>  (nitrogen is considered a<unk> " for plants, as it often is included in fertilizers). These four elements compose about 96% of the weight of the human body, and major<unk>  (macrominerals) and minor<unk>  (also called trace elements) compose the remainder. Nutrient<unk> , being elements, cannot be synthesized biochemically by living organisms. Plants get<unk>  from soil. Most of the<unk>  in a human diet come from eating plants and animals or from drinking water. As a group,<unk>  are one of the four groups of essential nutrients, the others of which are vitamins, essential fatty acids, and essential amino acids. The five major<unk>  in the human body are calcium, phosphorus, potassium, sodium, and magnesium. All of the remaining elements in a human body are called "trace elements". The trace elements that have a specific biochemical function in the human body are sulfur, iron, chlorine, cobalt, copper, zinc, manganese, molybdenum, iodine, and selenium. Most chemical elements that are ingested by organisms are in the form of simple compounds. Plants absorb dissolved elements in soils, which are subsequently ingested by the herbivores and omnivores that eat them, and the elements move up the food chain. Larger organisms may also consume soil (geophagia) or use<unk> resources, such as salt licks, to obtain limited<unk>  unavailable through other dietary sources. Bacteria and fungi play an essential role in the weathering of primary elements that results in the release of nutrients for their own nutrition and for the nutrition of other species in the ecological food chain. One element, cobalt, is available for use by animals only after having been processed into complex molecules (e.g., vitamin B12) by bacteria.<unk>  are used by animals and microorganisms for the process of<unk> zing structures, called biomineralization, used to construct bones, seashells, eggshells, exoskeletons and mollusc shells.
