Which chemical form is dominant in the phosphorus cycle?
“Phosphate ion” for which chemical form is dominant in the phosphorus cycle. This relationship follows from the ecological mechanism represented by the terms in the item, not merely from an association between their names. Rates depend on temperature, moisture, substrate quality, consumer physiology, and the elemental balance between organisms and their food. These controls explain why the same process can differ among terrestrial, freshwater, and marine systems without changing its definition. The remaining alternatives—“Phosphine gas”, “Elemental phosphorus”, “Phosphoric acid”—refer to diffe
