| 13270846310 | transpiration | the release of water from leaves during photosynthesis |  | 2 |
| 13270846311 | evapotranspiration | the combined amount of evaporation and transpiration |  | 3 |
| 13270846312 | runoff | water moves across the land surface into streams and rivers |  | 4 |
| 13270846313 | carbon cycle | the movement of carbon around the biosphere |  | 5 |
| 13270846314 | macronutrient | one of six key elements that organisms need in relatively large amounts: nitrogen, phosphorus, potassium, calcium, magnesium, and sulfur | 6 | |
| 13270846315 | limiting nutrient | a nutrient required for growth of an organism but available in lower quantity than other nutrients | 7 | |
| 13270846316 | nitrogen cycle | the movement of nitrogen around the biosphere | 8 | |
| 13270846317 | nitrogen fixation | a process by which some organisms can convert nitrogen gas molecules directly into ammonia | 9 | |
| 13270846318 | nitrification | the conversion of ammonia (NH4+) into nitrite (NO2-) and then into nitrate (No3-) ammonia>>nitrite>>nitrate | 10 | |
| 13270846319 | assimilation | the process by which producers incorporate elements into their tissues | 11 | |
| 13270846320 | mineralization | the process by which fungal and bacterial decomposers break down the organic matter found in dead bodies and waste products and convert it into inorganic compounds | 12 | |
| 13270846321 | ammonification | the process by which fungal and bacterial decomposers break down the organic nitrogen found in dead bodies and waste products and convert it into inorganic ammonium (Nh4+) | 13 | |
| 13270846322 | denitrification | the conversion of nitrate in a series of steps into the gases nitrous oxide and eventually nitrogen gas (n2) which is emitted into the atmosphere | 14 | |
| 13270846323 | leaching | the transportation of dissolved molecules thru the soil via groundwater | 15 | |
| 13270846324 | phosphorus cycle | the movement of phosphorus around the biosphere | 16 | |
| 13270846325 | algal bloom | a rapid increase in the algal population of a water way -eventually dies and decomposition consumes the oxygen the algae produced -the body of water becomes oxygen deprived aka HYPOXIC and turns into a dead zone -too much phosphorus results in this | 17 | |
| 13270846326 | hypoxic | low in oxygen | 18 | |
| 13270846327 | sulfur cycle | the movement of sulfur around the biosphere | 19 | |
| 13270846328 | d | which one of the following is fixed from the atmosphere by bacteria? a. magnesium b. phosphorus c. sulfur d. nitrogen e. potassium | 20 | |
| 13270846329 | 1,2 | human construction of buildings and placement affect the hydrological cycle by 1. increasing runoff 2. increasing evaporation 3. increasing percolation | 21 | |
| 13270846330 | c | the largest carbon pool is found in a. oceans b. atmosphere c. sedimentary rock d. living organisms e. fossil fuels | 22 | |
| 13270846331 | a | phosphorus a. is a limiting nutrient in aquatic systems b. has an important gas phase c. is easily lost from soils due to leaching d. is often produced by volcanic eruptions e. changes chemical form often during its biogeochemical cycle | 23 | |
| 13270846332 | e | acid rain is associated with which geochemical cycle? a. potassium b. calcium c. carbon d. phosphorus e. sulfur | 24 | |
| 13270846333 | d | which of the following processes is also known as ammonification? a. nitrogen fixation b. nitrification c. assimilation d. mineralization e. denitrification | 25 |
