Phosphorus deficiency is a plant disorder associated with insufficient supply of phosphorus. Phosphorus refers here to salts of phosphates ( PO 3− 4 ), monohydrogen phosphate ( HPO 2− 4 ), and dihydrogen phosphate ( H 2 PO − 4 ).
Hypophosphatemia is an electrolyte disorder in which there is a low level of phosphate in the blood. [1] Symptoms may include weakness, trouble breathing, and loss of appetite. [1]
Phosphorus deficiency can produce symptoms similar to those of nitrogen deficiency, [35] characterized by an intense green coloration or reddening in leaves due to lack of chlorophyll. If the plant is experiencing high phosphorus deficiencies the leaves may become denatured and show signs of death.
Phosphorus is a member of the pnictogens, together with nitrogen, arsenic, antimony, bismuth, and moscovium, and consequently shares properties with them. Phosphorus is an element essential to sustaining life largely through phosphates, compounds containing the phosphate ion, PO 4 3−.
The resulting phosphorus deficiency in grizzly bear diets results in a skewed calcium to phosphorus ratio and creates an appetite for bone. Because this deficiency is associated with the cycle of the seasons, osteophagy in bears is likely to be a seasonal phenomenon rather than a constant dietary supplement. [3]
This condition can be caused by vitamin D, calcium or phosphorus deficiency. [86] Vitamin D deficiency remains the main cause of rickets among young infants in most countries because breast milk is low in vitamin D, and darker skin, social customs, and climatic conditions can contribute to inadequate sun exposure.

Phosphorus, required component of bones; essential for energy processing. [71] Approximately 80% is found in the inorganic portion of bones and teeth. Phosphorus is a component of every cell, as well as important metabolites, including DNA, RNA, ATP, and phospholipids. Also important in pH regulation.
