it decreases due to decay of plant and animal material
eutrotrophic
eutrophic lake
I want to say yes. Lake Michigan is not Oligotrophic like Lake George in New York. It isn't Eutrophic or Hypereutrophic which are characterized by high levels of nitrogen and phosphorus and low levels of oxygen near the bottom of the lake.
Add nutrients (phosphorus, nitrogen, etc.)
Found it. Its oligotrophic.
Oligotrophic refers generally to ecosystems which have very little nutrients to sustain life. These can be very salty lakes or soils with a very low nitrogen content.An oligotrophic lake is that with plenty of oxygen but deficient of nutrients for plant growth.
Decreases
Well this answers part ofthe Q. I did an experiment at uni that produced an oli. We had a final pH of about 8.2 ish
aquartic
Accumulation of organic matter. "Eutrophication occurs when fertilizers, animal waste, sewage, or other substance rich in nitrogen and phosphorus flow into waterways, causing extensive algae growth. The algae use up the oxygen supply during their rapid growth and after their deaths during the decaying process"
someone please answer this
Dead lake.
