Recommended: Effects of eutrophication
According to Harrison Eutrophication is the excessive production of algae and higher plants through the enrichment of waters by nitrogen and phosphorus. Phosphorus in the form of phosphate is the limiting nutrient as the amount of biologically available phosphorus is small in relation to the amount needed for algal growth. Harrison states that sources of nutrients can be discrete, (sewage), or diffuse, (farmland fertilizers).
One issue found is the creation of smelly phytoplankton that makes murky unclear waters along with aquatic impurities. Moreover, the reduction of growth due to poor light conditions and dying plants make it difficult for predatory fish to hunt leading to overpopulation. (Chislock, 2013) Eutrophication can be found in many of our water resources such as ponds, estuaries, and bays. One region with high areas with eutrophication is in a lake shared by Kisumu, Kenya and Kampala, Uganda.
They can consume up to one liter per day, some of the particles that are consumed are used for food but they mainly eat plankton. The other particles are combined with mucus,other matters which are deposited on the floor of the lake since they are useless to the Zebra Mussels. In this research we will be talking about how the Zebra Mussels Impacted the Great Lakes, and what the effects were and if they were positive or a negative effect. Results: 300-400 words Invasive species has always been documented to have negative harm to the environment but Zebra Mussels are invasive species that have a negative harm and also a positive effect to the environment.
Scientists believe that this is because the phytoplankton is being eaten by the Zebra mussel. This causes the zooplankton, who eat phytoplankton to die. This has made zooplankton present to go down by half. The smallest species of phytoplankton have died down by 90 present. Most other mussel in the Hudson have gone down for billions to almost none.
It’s hard to manage system when there are constant changes. A large change in Lake Michigan started about 25 years ago when Quagga Mussels got into the system. The bottom of the lake is now covered with them because the smooth surface and cold water is the ideal for habitat for quagga mussels to grow on. Quagga Mussels can filter up to four liters water per day.
THE GREAT LAKES The great lakes are comprised of 5 different fresh water lakes, Superior, Huron, Michigan, Ontario, and Erie. The lakes are situated along the US-Canadian border, touching Ontario in Canada and Michigan, Minnesota, Wisconsin, Illinois, Ohio Pennsylvania, Indiana and New York in the United States. Roughly 34 million people in Canada and the United States live in the great lakes basin, and also 35 000 plants and animals, over 170 of those being fish, inhabit the great lakes (Zimmermann). This significantly large water body holds an estimate of 6 quadrillion gallons of water.
The growth of manoomin in lakes helps an entire ecosystem to live from the bugs living off it to the snakes, frogs, and birds that use it to find food and shelter, creating a food chain for a whole ecosystem. Arthur explains this in the book when he says “You should see when I harvest bags of the stuff. Lots of bugs and insects crawling all through it… See, these insects live off the plants, and those that don't, live off the insects that do. Add to that all the birds, frogs, snakes, and other animals that consider manoomin a food court because of those insects.” (Taylor 29)
Identify the problem: In a vast array of Michigan lakes, a crusty brown algae is spoiling the waters it comes into contact with. (Some lakes include Torch Lake, Elk Lake, and Lake Charlevoix). Pinpoint Causes of the Problem: From an undetermined source, groundwater nutrients nutrients like nitrogen and phosphorus are penetrating the lake at abnormal levels. However, a few leads have been suspected. These culprits include invasive mussels, heavy ice cover the last two years, residential and agricultural runoff, and outdated septic systems.
The argument in an article has a strong effect depending on the language and style the author is using to persuade the audience. In “Sprawl Is Harmful to Wildlife” Jutka Terris argues that urban sprawl is affecting wildlife. Loss of habitat is occurring while people move to the suburbs. Terris must know how to approach towards the audience; it has to be in a manner that will make them believe her argument is correct. Terris argues these statements because she wants to reach out to an audience that agrees to the same problem.
THE ZEBRA MUSSEL INCIDENT The Zebra Mussel Incident Zebra Mussels are an invasive species which now dominate the Great Lakes region, they were introduced in the 1980’s and ever since then their quantities have increased dramatically. Since the time they arrived they have caused many problems including problems in the ecosystem and with the economy. Human’s have been trying ever since their arrival to eliminate or reduce their quantities but not much progress has been made. Right now Zebra Mussels are one of the biggest issues affecting the great lakes.
The Swan at Edgewater Park by Ruth L. Schwartz has one major message that it is trying to get across. I believe that the poet is trying to say that beauty isn't just skin deep, but that regardless of what they look like on the outside a person can still be beautiful on the inside. The line that gave this impression the most was the line where she says “Beauty isn't the point here; of course the Swan is beautiful.”. Schwartz is acknowledging the fact that swans are physically beautiful, but more than just the physical aspect of beauty Schwartz is talking about the swans inner beauty. In the very first line of the poem Schwartz explains to the reader “ Isn't one of your prissy rich people's swans” she dispels any connotation the reader
Gilded age Gilded age coastline has been losing its wetlands at a rate of 16.57 square miles a year during the past 25 years, equal to the loss of a football field of coast every hour. This loss of wetlands is due to pollution, deforestation, and erosion. The loss has caused has caused loss of biodiversity. Louisiana has lost 1900 years ago of land because of pollution from landfills, factory waste, and erosion.
With the gradual decomposition of mulch throughout the year, valuable nutrients are lost to both plants and their creepy-crawly
Tundra comes from the Finnish word "tunturia", which means a barren land. The ground is permanently frozen 10 inches to 3 feet (25 to 100 cm) down so that trees can 't grow there. The bare and sometimes rocky ground can only support low growing plants like mosses, heaths, and lichen. In the winter it is cold and dark and in the summer, when the snow and the top layer of permafrost melt, it is very soggy and the tundra is covered with marshes, lakes, bogs and streams that breed thousands of insects and attract many migrating
Most people would say it 's all in our heads and to leave it alone buts its a serious issue. Last but not least, it’s hard to get rid of these species because they 've been here for so long they multiplied scenes then. In conclusion to, this is why i think zebra mussels are the worst invader species.
