Over 95% of the Earth's phosphorus is stored in sedimentary rock, a finite resource that is not immediately accessible. This makes the natural process of rock weathering a major source of phosphorus in ecosystems, though modern agriculture and diet have introduced significant human-driven sources.

Bicarbonate is the dominant form of dissolved inorganic carbon in seawater and most freshwater systems. This crucial ion originates from a variety of interconnected natural sources, including the constant chemical weathering of rocks, ancient mineral deposits, and the metabolic activities of living organisms.
