NH3, used by plants
NH4, used by plants
N2, 78% of atmosphere
NO, converted to NO2
N20, depletes the ozone
NO3, absorbable by plants
NO2, major greenhouse gas
O2, breathable, 21% of atmosphere
O3, blocks UV in the stratosphere
CO2, major greenhouse gas
PO43-, Plant Nutrient
Ca3PO4, bone salt
HCO3-, dissolved CO2 in the ocean
H2S, highly poisonous
SO42-, absorbable by plants
SO3, between DMS and H2SO4
H2SO4, acid rain
dimethyl sulfide DMS
CH3SCH3, product of marine algae
trophic level that has most usable energy
trophic level contains the most biomass
nutrient that does NOT have an atmospheric component
nutrient typically the limiting growth factor
8 levels of ecosystem
fuel source with the most sulfur
humans directly adding carbon into atmosphere
breathing & driving a car
humans indirectly adding carbon into atmosphere
cutting down trees
more water = ?
way a biome is classified
climate type & dominant plant life
2 usable forms or nitrogen
ammonia and nitrates
2 things that drive the hydrologic cycle
gravity and the sun
what would happen to the nitrogen cycle if BACTERIA were not involved?
none of the processes would happen
nitrogen compounds converted to ammonia and nitrates
bacteria convert AMMONIUM into nitrates
plants absorb NH3, NH4, & NO3 through the roots
bacteria convert ammonia back into usable forms
increased concentration of a deadly poison that occurs in food chains
which nutrients create acid rain when released into the atomosphere?
nitrogen and sulfur
nutrient cycle is slow with components in rocks and the atmosphere?
lose leaves in the winter?
process removed N2 from the atmosphere?
process brings nitrogen into the food chain?
process releases nitrogen back into atmosphere?
primary energy source in a deep sea thermal vent
specific nutrient will induce increased cloud cover near large bodies of water
always on top of the food chain
