Lithium is a member of the alkali metals family of elements, which includes (along with Li) sodium, potassium, rubidium, caesium, and francium.  Of the minor elements exhibiting nutrient-type depletion profiles in recirculating marine ecosystems, Lithium is present in natural seawater at the highest concentration, followed by Rb, I, Ba, and Mo, respectively.  Potential mechanisms for lithium depletion include, but are not limited to, uptake by phytoplankton and other primary producers (including zooxanthellae), and incorporation into zooplankton tests and calcareous minerals, including aragonite (both biogenic and authigenic).  Whether the depletion occurs inadvertently, as a result of competition for other ions with similar characteristics of charge and radius, or is a result of intentional uptake and/or complexation, is likely circumstantial, e.g. influenced by a variety of factors in a continual state of flux in marine ecosystems, of which the specific ionic profile of the system likely plays the largest role.  Due to the largely unpredictable extent to which lithium plays a role in biochemical reactions taking place within the marine environment, the primary purpose of establishing and maintaining the standardized value of Li within a recirculating marine ecosystem is to achieve a greater degree of similarity to natural seawater, enabling the ion to remain available for uptake as necessary.​
