36. biogeochemical cycles
|
Because these pathways all lead in circles and involve biological geological and chemical processes
|
|
37. carbon cycle
|
through photosynthesis and further metabolism carbon atoms from CO2 become the carbon atoms of the organic molecules making up a plant’s body.
|
|
38. phosphorus cycle
|
Representative of the cycles of all the biologically important mineral nutrients those elements that have their origin in the rocks and soil minerals of the lithosphere such as iron calcium and potassium.
|
|
39. organic phosphate
|
once the phosphate is incorporated into organic compounds by plants
|
|
40. nitrogen cycle
|
has aspects of both the carbon cycle and phosphorus cycle
|
|

|
he main reservoir of nitrogen is the air which is 78% nitrogen gas.
|
|
42. reactive nitrogen
|
the remaining forms of nitrogen
|
|
43. nitrifying bacteria
|
A group of soil bacteria oxidizes the ammonium to nitrate in a chemosynthetic process that yields energy for bacteria.
|
|
44. nitrogen fixation
|
A number of bacteria and cyanobacteria can use nonreactive N
|
|
46. atmospheric nitrogen fixation
|
one is the conversation of nitrogen gas to the ammonium forms by discharges of lightning
