Eutrophication
Eutrophication is usually the result of fertilisers being washed into a body of water e.g. lake or river.
1) farmers add fertilisers (containing nitrates and Phosphates) to their crops to help them grow.
2)Heavy rain washes the fertilisers off and the nitrates and phosphates dissolve.
3) The nitrates and phosphates that aren't taken up by plants are washed into a stream or river.
4)The high concentrations of phosphates and nitrates encourage rapid plant and algae growth.
5) surface plants (in the body of water) block sunlight. so plants in the water can't photosynthesize and die (so no more oxygen is being made through photosynthesis.)
6) the decomposing bacteria that break down the dead plants thrive (because of all the dead plants) and use up more oxygen.
7) oxygen concentrations in the water decreases and animals (e.g. fish) die due to lack of oxygen.
What else can I help you with?
What are the importance of oligotrophic and eutrophic lakes?
someone please answer this
How does an oligotrophic lake become eutrophic?
Add nutrients (phosphorus, nitrogen, etc.)
Fish found in eutrophic waters?
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.
Are all plantlike protists always eutrophic?
No, not all plantlike protists are eutrophic. Eutrophication refers to an excess of nutrients in the environment, which can lead to algal blooms. Plantlike protists can be found in various types of habitats, not just eutrophic ones.
What is the difference between an oligotrophic and a eutrophic lake?
eutrotrophic
Are all plantlike protists are always eutrophic?
Yes, all plant like protists are always eutrophic. This includes diatoms, and dinoflagellates. This is because they are all part of the algae family.
Is the Hudson considered eutrophic?
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.
What is the difference between an oligotrophic and eutrophic environment?
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.
How can lakes become dry land?
evaporation
What happens to the oxygen in a eutrophic lake?
it decreases due to decay of plant and animal material
A lake in which minerals are scarce is profundal oligotrophic eutrophic benthic pelagic?
Found it. Its oligotrophic.
Do lakes near volcanoes become acidic?
Yes.
