The Phosphorus Cycles

All living require what because it is needed to make such things as what and what. It is also found in the bones teeth and shells of many what

All living require PHOSPHORUS because it is needed to make such things as ATP and DNA. It is also found in the bones teeth and shells of many ANIMALS

Phosphorus tends to cycle what in an ecosystem, but it can be part of a what cycle

Phosphorus tends to cycle SLOWLY in an ecosystem, but it can be part of a SHORTER cycle

Soil and rocks are the main what for phosphorus. Rock weathering gradually adds what to the soil in the form of what, which what can absorb

Soil and rocks are the main RESERVOIRS for phosphorus. Rock weathering gradually adds PHOSPHORUS to the soil in the form of PHOSPHATE (PO4) , which PLANTS can absorb

Absorb what is then transferred to consumers in what form (DNA, RNA)

Absorb PHOSPHORUS is then transferred to consumers in ORGANIC form (DNA, RNA)

Phosphorus is returned back to the soil by animal what and the action of what. Soil particles and humus (organic material in soil) binds what so it is not leached out into the water table, and the phosphate is what by plants

Phosphorus is returned back to the soil by animal EXCRETION and the action of DECOMPOSERS. Soil particles and humus (organic material in soil) binds PHOSPHATE so it is not leached out into the water table, and the phosphate is REABSORBED by plants

Some phosphate gradually does leach out into the water table and eventually makes it down to the bottom of the what where it accumulates. Geologic uplift returns ocean bottom what back to the surface over geologic time.
