Remainder "trace elements", have a specific biochemical function in the human body are iron, cobalt, copper, zinc, manganese, molybdenum, iodine, and selenium.
Most chemical elements ingested by organisms are in the form of simple compounds.
Plants absorb dissolved elements in soils, which are subsequently ingested by the herbivores that eat them, and the elements move up the food chain.
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.
Cobalt, is available for use by animals only after having been processed into complex molecules (e.g., vitamin B12) by bacteria.
The process of mineralizing structures, called "biomineralization", used to construct bones, seashells, eggshells, exoskeletons and mollusc shells.
