MFWB_A - Primary Production and Eutrophication

biological oxygen demand

amount of dissolved oxygen needed by aerobic organisms to break down organic material present in water sample at certain temp/time period

eutrophy/hypertrophy

depth of lake decreases due to build up

bottom up control

nutrients controlled to influence primary productivity

top down control

introduce species to control biomass in indirect ways

coastal waters

N is the limiting factor, deltas and salt marshes naturally eutrophic, coastal upwelling increases productivity
