matter

Anything that occupies space, and has mass
7. biosphere
Three open systems or “spheres” occupied by living things
8. lithosphere
Earth’s crust made up of rocks and minerals.

hydrospere

is water in all of its liquid and solid compartments
10. atmosphere
Is thin layers of gases separating earth from outer space
11. key elements of living things
Carbon, Hydrogen, Oxygen,Nitrogen,Phosphorus, Sulfur
13. organic compounds
The chemical compounds making up the tissue of living organisms
14. inorganic compounds
Molecules of compounds that is those with neither carbon--carbon nor carbon--hydrogen or carbon--oxygen bonds
17. energy
the ability to move matter
18. kinetic energy
energy in action or motion
19. potential energy
energy in storage
31. fermentation
when decomposer meet their energy nees through the partial breakdown of glucose that can occur in the absence of oxygen
32. anaerobic
oxygen free environment
33. energy flow
in an ecosystemIsn’t recycled must be resupplied by sunlight
34. energy efficiency
in an ecosystemTransferred from one trophic level to the next
35. solar energy
Energy collected from the sun that is absorbed by solar panels
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
41. non-reactive nitrogen
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
47. industrial nitrogen fixation/ Haber-Bosch process
in the manufacture of fertilizer the process converts nitrogen gas and hydrogen ammonia
48. combustion of fossil fuels and nitrogen
oxidesduring which nitrogen from coal and oil is oxidized
49. denitrification
a microbial process that occurs in soils and sediments depleted of oxygen
50. global nitrogen fertilization rate compared to natural rate
acid deposition
