APES Flashcards

15114282881	carbon in abiotic environment	-atmosphere -dissolved in water -calcium carbonate in rocks -deposits of coal, petroleum, and natural gas from fossilized organisms -dead organic matter (humus)	0
15114349988	carbon cycle major reservoirs/sinks	-rocks/sediment (includes fossil fuels) -ocean -biosphere (plants, animals, soil) -atmosphere	1
15114371289	carbon enters biotic world thorugh	photosynthesis and chemosynthesis (archaebacteria)	2
15114386082	carbon returns to atmosphere by	-cellular respiration -burning -decay and decomposition	3
15114403835	largest carbon sink	ocean	4
15114414033	nitrogen fixation	organisms convert nitrogen gas to ammonia	5
15114417515	nitrification	conversion of ammonia into nitrite and then intro nitrate	6
15114423191	N assimilation	-producers take up either ammonium or nitrate -consumers assimilate by eating producers	7
15114438197	ammonification	decomposers break down organic nitrogen into inorganic ammonia	8
15114452956	dentrification	denitrifying bacteria convert nitrate into nitrogen gas	9
15114467181	largest nitrogen sink	atmosphere	10
15114474735	human impact of nitrogen cycle	-nitrogen in limited in most terrestrial ecosystems -leaching is when dissolved molecules are transported through soil via groundwater -increase in fertilizer	11
15114497715	Nodules containing nitrogen-fixing bacteria would be expected to occur on the roots of	legumes	12
15114588748	phosphorus cycle	-water precipitates out of oceans as sediments -over time, sediment becomes mountain -mountains are weathered by rain, etc. -weathering brings phosphorus to terrestrial and aquatic environments -held tightly by soils so it is not easily leached by soil	13
15114613554	P assimilation	producers on lands and in water take up inorganix phosphate	14
15114623947	there is no phosphorus in the...	atmosphere	15
15114632411	P human impacts	-phosphorus mining -agal bloom -dead zone -household detergents	16
15114654555	important storages of phosphorus	soil and oceans	17
15114686336	largest phosphorus reservior	rocks	18
15114659463	carbon importance	makes up macromolecules for energy	19
15114672858	nitrogen importance	makes up our DNA, proteins, etc. that is needed for structure	20
15114677288	phosphorus importance	makes up ATP and RNA	21
15114733532	large water reservior	ocean	22
15114733533	small water reservoir	groundwater and ice caps	23
15114747997	percent of earth's water supply available as liquid freshwater	2.5%	24
15114769127	runoff	-Water that moves across the land surface and into streams and rivers -land to sea	25
15114776130	infiltration	-the process by which water on the ground surface enters the soil -ground to soil	26
15114783410	precolation	-downward flow of groundwater through soil and rock -soil to groundwater storage (aquifer)	27
15114793369	evaporation	liquid to gas	28
15114796399	transpiration	-in plants -liquid to gas	29
15114803951	condensation	gas to liquid	30
15114807301	percipitation	gas to liquid/solid	31
15114827664	watershed	land area that delivers runoff to a stream	32
15114840025	groundwater	precipitation infiltrates the ground and is stored in soil/rock	33
15114846833	surface runoff	water that does not sink into the ground or evaporate, runs off into bodies of water	34
15114857404	aquifer	underground cavern which groundwater flows	35
