Phosphorus Cycle
Phosphorus was discovered by
Hennig Brand at 1669 in
Germany. Origin of name: from
the Greek word "phosphoros"
meaning "bringer of light"
Brand kept his process a
secret, phosphorus was
discovered independently
in 1680 by an English
chemist, Robert Boyle.
•Atomic Number: 15
•Atomic Weight: 30.973762
•Melting Point: 317.30 K (44.15 C or 111.47 F)
•Boiling Point: 553.65 K (280.5 C or 536.9 F)
•Density: 1.82 grams per cubic centimeter
•Phase at Room Temperature: Solid
•Element Classification: Non-metal
•Period Number: 3
•Group Number: 15
•Group Name: Pnictogen
A multivalent pnictogen, phosphorus
as a mineral is almost always present
in its maximally oxidised state, as
inorganic phosphate rocks.
Elemental phosphorus exists in two
major forms—white phosphorus
and red phosphorus—but due to its
high reactivity, phosphorus is never
found as a free element on Earth.
In nature, Phosphorus exists in form
of phosphate.
White Phosphorus is used in
some explosives, including
rockets. This caused an uproar
because of safety concerns.
Red Phosphorus is used in
match heads. You can see
the texture of a match head
next to the matches.
Fertilizer; Phosphorus is
known for being essential
to DNA and to a lesser
extent fertilizer
 It is an essential nutrient for plants and animals.
 It is a part of DNA-molecules and RNA-
molecules, molecules that store energy (ATP and ADP)
 It is also a building block of certain parts of the
human and animal body, such as the bones and teeth.
• Ecological Function
 Phosphorus is an essential nutrient for plants and animals.
 Limiting nutrient for aquatic organisms.
 Forms parts of important life-sustaining molecules that are
very common in the biosphere.
• Biological Function
 The primary biological importance of phosphates is as
a component of nucleotides, which serve as energy storage
within cells (ATP) or when linked together, form the
nucleic acids DNA and RNA..
The biogeochemical cycle that describes
the movement of phosphorus through
the lithosphere, hydrosphere, and biosphere. Unlike
many other biogeochemical cycles,
the atmosphere does not play a significant role in
the movement of phosphorus, because phosphorus
and phosphorus-based compounds are usually
solids at the typical ranges of temperature and
pressure found on Earth.
Phosphorus cycle
1. When rocks high in
phosphorus are exposed to
water, the rock weathers out and
goes into solution
2. autotrophs absorb this
phosphorus and use it in many
different ways,
3. then the plant is eaten by a
heterotroph and obtains
phosphorus from the plant
4. then the phosphate leaves the
body, and decomposers move the
phosphorus into the soil or water
then another plant will absorb
this phosphorus.
