Terms | Definitions |
|---|---|
 ammonia | NH3, used by plants |
| ammonium ion | NH4, used by plants |
| nitrogen | N2, 78% of atmosphere |
| nitric oxide | NO, converted to NO2 |
| nitrous oxide | N20, depletes the ozone |
| nitrate | NO3, absorbable by plants |
| nitrogen dioxide | NO2, major greenhouse gas |
| oxygen gas | O2, breathable, 21% of atmosphere |
| ozone | O3, blocks UV in the stratosphere |
| carbon dioxide | CO2, major greenhouse gas |
| carbon monoxide | CO, POISONOUS |
| Phosphate | PO43-, Plant Nutrient |
| calcium phosphate | Ca3PO4, bone salt |
| bicarbonate | HCO3-, dissolved CO2 in the ocean |
| hydrogen sulfide | H2S, highly poisonous |
| sulfur dioxide | SO2, POLLUTANT |
| sulfate | SO42-, absorbable by plants |
| sulfur trioxide | SO3, between DMS and H2SO4 |
| sulfuric acid | H2SO4, acid rain |
| dimethyl sulfide DMS | CH3SCH3, product of marine algae |
| trophic level that has most usable energy | producer |
| trophic level contains the most biomass | producer |
| nutrient that does NOT have an atmospheric component | phosphorus |
| nutrient typically the limiting growth factor | phosphorus |
| 8 levels of ecosystem | atom->molecule->cell->organism->population->community->ecosystem->biosphere |
| fuel source with the most sulfur | coal |
| humans directly adding carbon into atmosphere | breathing & driving a car |
| humans indirectly adding carbon into atmosphere | cutting down trees |
| more water = ? | MORE LIFE! |
| 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 fixation | nitrogen compounds converted to ammonia and nitrates |
| nitrification | bacteria convert AMMONIUM into nitrates |
| assimilation | plants absorb NH3, NH4, & NO3 through the roots |
| ammonification | making AMMONIA |
| denitrification | bacteria convert ammonia back into usable forms |
| biomagnification | 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? | sulfur cycle |
| lose leaves in the winter? | deciduous trees |
| grazing animals? | grasslands |
| process removed N2 from the atmosphere? | nitrogen fixation |
| process brings nitrogen into the food chain? | assimilation |
| process releases nitrogen back into atmosphere? | dentrification |
| CFC | chlorofluorocarbon |
| chemosynthesis | primary energy source in a deep sea thermal vent |
| dimethyl sulfide | specific nutrient will induce increased cloud cover near large bodies of water |
| decomposers | always on top of the food chain |
