BIOL 440 Lecture Notes - Lecture 6: Nitrogen Cycle, Harmful Algal Bloom, Phospholipid
Document Summary
Atmospheric n2 fixation: lighting energy and heat converts n2 to no2. Denitrification: leave the ecosystem and enters the atmosphere. + no2: mineralization: organic n nh4, n immobilization is the opposite, nh4. No n2o n2: high in environments with low o2 and plenty of. No3: ex. deep ocean, pantanal wetland, wet soils with high no3, enhanced denitrification by wetting and drying. Levels (alternating nitrification and denitrification: effects, helps to alleviate n pollution in aquatic and terrestrial ecosystems, no3. : harmful in drinking water and causes algal blooms: no: precursor to ozone formation in troposphere (where we are, n2o: potent greenhouse gas that destroys ozone in stratosphere. 3-) form: mineralization: fungi and bacteria break down detritus, release po4. Particular p: p captured on filter, including organic and inorganic. Soluble reactive p (srp): dissolved p passing through 0. 45 um membrane (primarily inorganic po4.
