|
What is Assimilation |
NO3- is absorbed by plants |
|
|
Assimilation - What is the NO3- converted to? |
Protein, DNA + RNA, Chlorophyll, or ATP |
|
|
Ammonification |
N-waste converted to NH3 or NH4+ |
|
|
What converts the organic nitrogenous waste to NH3 or NH4+? |

|
Denitrification |
NO2 or NO3 -> NH3 or NH4 -> N2 |
|
|
What are some Facultative Anaerobes? |
Swamps, Marshes. and Waterlogged Soil |
|
|
What are some Human impacts? |
Inorganic Fertilizer - kills N-fixing bacteria or runoff causes eutrophication Burning Fossil Fuels - releases NOx Erosion- runoff causes eutrophication Human Sewage Output Animal Farms- Factory farms produce to much Clear Cutting Forest - Erosion -> Runoff -> Eutrophication and increased leaching |
