Definition
| phosphorus cycle: measured imports and exports of nutrients to soil |
|
|
Term
| Be familiar with Bear Brook and when it gains and loses P |
|
Definition
| - phosphorus cycle has greatest gains during leaf fall, greatest losses during rain storms or snowmelt |
|
|
Term
| Be familiar with anthropogenic effects on P cycle |
|
Definition
| phosphorus export increases as land use intensifies |

|
Term
| Be familiar with nitrogen fixation and the organisms / process that fixes N |
|
Definition
- To fix nitrogen means to go from N2 to NH3 (ammonia), which allows living organisms to use it;
organisms that fix: 1. Cyanobacteria, 2. Free-living soil bacteria, 3. Symbiotic bacteria on legumes, 4. Symbiotic bacteria on woody plants

| Be familiar with deforestation effects on N and population density on N export from streams |
|
Definition
| - nitrogen loss from the forest was much higher after deforestation |
|
|
Term
|
Definition
the last step in the nitrogen cycle where the reduction of soil nitrate to nitrogen-containing gases, such as nitrate oxide nitrous oxide and nitrogen gas takes place
microbes use nitrate to live and nitrogen is released.
