phosphorous cycle Flashcards
why is phosphorous important
important in atp and nucleic acid and dna
where does the phosphorous originally come from
the sediments of rocks and its deposits as phosphorous ions , the wethering of rocks make them dissolve in the water so available for absorption which incoroporate them into their biomass
how are the phosphate ion transported to the animals
when they feed on the plant
how are the phosphate ions returned back to the soil
excess phosphate ions are excreted through animal waste and guano from sea birds
what do decomposers do
they break down the excretory material and dead material releasing phosphate ions into the soil and water
what happens to the phospite ions from excretory waste t
they are released by decomposition and are dissolved by water they flow into the river and lakes and then form sedimentary rocks
what do mycorrhizae provide for the nutrient cycle
they act like extensions for the roots increasing its surface area for the absorption of water and minerals and it can act like a sponge holding the water and minerals near the roots s it can take up water more reasily
and the fungus gets sugars from the plant
