it decreases due to decay of plant and animal material
eutrotrophic
A eutrophic lake is rich in organic matter and vegetation, leading to poor oxygen levels due to decomposition processes. This can result in algal blooms and a decrease in biodiversity as oxygen levels decline.
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.
A eutrophic lake is a type of lake that is rich in organic matter and vegetation but often has poor oxygen levels due to high nutrient inputs. The excess nutrients, such as phosphorus and nitrogen, stimulate excessive plant growth, leading to oxygen depletion as the plants decompose.
Add nutrients (phosphorus, nitrogen, etc.)
Found it. Its oligotrophic.
Some common fish that can be found in eutrophic waters include carp, bullhead catfish, and bluegill. These fish are more tolerant of the lower oxygen levels and higher nutrient concentrations typically found in eutrophic environments. However, eutrophic conditions can lead to algal blooms that may be harmful to fish populations in the long term.
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.
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
The lake is likely experiencing eutrophication, where excess nutrients like nitrogen and phosphorus are present, leading to increased plant growth. This can result in algal blooms, reduced oxygen levels, and negative impacts on aquatic life. Efforts to reduce nutrient inputs, such as from agriculture or sewage, are important to restore the lake's ecological balance.
The Hudson River is generally not classified as eutrophic, though certain sections may experience localized eutrophic conditions due to nutrient runoff, especially near urban areas. Eutrophication is characterized by excessive nutrient enrichment leading to algal blooms and oxygen depletion. While some areas of the river may show signs of nutrient enrichment, the overall health of the Hudson varies and is actively monitored to manage any potential eutrophic impacts.
Lake Mead is generally considered a mesotrophic to eutrophic lake, rather than oligotrophic. Oligotrophic lakes are characterized by low nutrient levels and high oxygen content, typically supporting fewer aquatic plants and animals. In contrast, Lake Mead has experienced fluctuations in nutrient levels due to factors like runoff and water management practices, leading to increased productivity in some areas. Therefore, it does not fit the criteria for being classified as oligotrophic.
