Note 10: Nutrient Cycling in Freshwater
Terms in this set (8)
what is the Mississippi River incident?
the nitrogen fertilizers runoff into the big lakes from little rivers
what happens to the oxygen when nitrogen levels are high?
respiration occurs more frequently and oxygen levels deplete causing fish to die
why is N limiting for marine?
in marine environments there is a decrease in FeOH which Pi likes to bind to, so there is a lot of Pi in the system
why is P limiting for freshwater?
increase in FeOH and Pi binds and there is less free Pi floating in the system
what is nutrient spiraling?
the process of atoms moving downstream due to currents
what is Turnover in nutrient spiraling?
nutrient uptake in sediment
what is the difference between organic and inorganic in turns of nutrient spiraling?
organic is immobile and inorganic is mobile
what is the Walker Branch Experiment?
release of P32 into water and measure the uptake by various organisms
