Eutrophication Essays

The Issue Eutrophication is the process of a lake or pond absorbing and/or being fed with nutrient-rich run-off from streams around agricultural areas. Nutrients causes the growth of plankton and bacteria, hence the death of bottom-dwelling pond plants and fish. Eutrophication is occurring in coastal environments and affecting the fish and plants living beneath the algae. A place where this is occurring is the Gulf of Mexico, where there is little life beneath the surface. Cause and Consequence Overall

conditions were good, warm and sunny. A series of tests were done to determine water quality. One test conducted was the measure of nitrate in the water. If there is too much nitrate it grows algae which is then eaten by bacteria, and can cause Eutrophication. Another test was done to determine the amount of BOD, which shows how much dissolved oxygen is needed by Aerobic bacteria in order to break down material. Ph is responsible for how acidic or basic the water is. If a body of water has a high ph

-1504A -07) Instructor: Trena Woolridge Unit 4- Discussion Board Amanda Kranning October 27, 2015 Eutrophication is a syndrome of ecosystem responses to human activities that fertilize water bodies with nitrogen (N) and phosphorus (P), often leading to changes in animal and plant populations and degradation of water and habitat quality.(Cloern, Krantz, & Hogan, 2013) Eutrophication forms when an abundance of nitrogen and phosphorus increases growth within an environment. One issue found

Yasmin Givens Introduction The purpose of this experiment is to investigate the effects and results of agricultural runoff, as well as how varying types of fertilizer (conventional and time-released) may affect the ever-growing problem of eutrophication. If the conditions of agricultural runoff are simulated, then the algae will grow plentifully and consequently kill the other life in the water. If the different types of fertilizer are tested (conventional and time released), then the time released

The third test we conducted were eutrophication tests, phosphate and nitrate tests, and acidity and alkalinity tests. The first one was a ph meter test to see if the water in the creek was acidic, neutral, or alkaline. On the ph meter we got a 7 which is neutral, and that’s good. For the alkalinity

Dissolved Oxygen (DO) is one of the most crucial properties of water quality; the oxygen dissolved in a body of water is used by all of the life within. Fish, plankton, bacteria, and other organisms in a body of water need oxygen for their cellular (and macro) respiratory systems. Without sufficient levels of oxygen in the water, life could not live within (src). 4-5 mg/L is the minimum DO concentration that can accommodate a variety of fish populations, and a large shift of DO can have drastic effects

• Duckweed (Lemna minor) is a member of the Lemnaceae family (Monette et al. 2006) it is a small plant that floats on the surface of still or stagnant water that is usually rich in nutrients (Keddy 2010). It was seen that Duckweed thrived in areas of high nutrient content, high sunlight and warmer temperatures (Taylor 2011) .It was also seen that fertilisers contained nutrients, such as nitrates, which greatly influences duckweed growth. Duckweed is also used for feed for farm animal, such as ducks

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

environment follows up. This has caused the loss of profits in tourist industry and increased the cost of fresh clean water in China. One of the most severe problem caused by agriculture goes towards the environment and human society is eutrophication. Eutrophication describes the situation of excessive richness of nutrients in water body, which mainly caused by human activities. Due to the fact that environmental

Lake Erie In the 1960’s, Lake Erie was covered with algae blooms. Lake Erie is now almost 241 miles of green. “Decades ago, 64 million pounds of phosphorus flowed into lake erie every year because of sewer outlines, industrial trash, and fertilizer/pesticides from farm runoff.” (Michael Wines) Farmers use pesticides and fertilizers to get rid of pests and help their plants grow. Except that all that runoff leads to one problem. It flows into nearby waters. For us, it’s Lake Erie. Lake Erie’s conditions

Introduction Our aim of this experiment is to determine how eutrophication affects the growth of duckweed by adding different concentrations of fertilizers to the water with different types and forms of fertilizer keeping it in set conditions for a period of two months to observe how eutrophication affects the growth of duckweed. Thus our hypothesis for this aim is that it is expected that eutrophication would affect the growth of duckweed when different concentrations of fertilizers are added to

Introduction: The Everglades is a national park that protects numerous of species and endangered species, for example, the Florida manatee, American crocodile, and Florida panther. According to Everglades foundation.Org, the Florida Everglades is the largest subtropical wetland in the United States, an international biosphere Reserve, and home to 73 threatened species are endangered species. The Everglades flows from the bottom of Orlando through Lake Okeechobee South to the tip of Florida Peninsula

My goal is to decrease the amount of nitrates in river systems. Explain the science of the problem that is created by the indicator. Eutrophication Eutrophication is a process that occurs as a result of this indicator. When farmers use fertilizers with nitrates on their crops, the rain washes the nitrates into the river. This excessive amount of nutrients causes the plants to grow rapidly. Now that these plants have grown so large, they block the sunlight. The underwater plants are deprived of

This lab uses a lake simulation to study how the addition of nutrients and toxins can affect the lake, its inhabitants and the surrounding area. There is a strong focus on the addition of Phosphorous and added toxins because both are key elements in growth in lakes. The Virtual lake includes these five simulated species; green algae, cyanobacteria, bosmina, daphnia, and trout. There are two types of phytoplankton in the lake model, green algae and cyanobacteria. Green algae are a very diverse group

Using Daphnia to Detect Water Safety Due Date: Monday, the 31th of October, 2017 INTRODUCTION Question: Can Daphnia be used to detect water pollution? How does the water type (source) affect the number of Daphnia and the accuracy and efficiency of testing water safety? Purpose: The purpose of this project is to test different water sources for safety using the Daphnia species. This is important to the local people of Santa Barbara because it can be used to test whether the water & soil sources

Hypothesis: Based on the location and data from abiotic and biotic organisms, sites with a poor water flow will have more polluted water. Methods: To test this hypothesis, several groups scattered along the lagoon to test the biotic and abiotic characteristics. Each group was stationed at different lengths along the lagoon. The locations for the groups ranged from 0 yards away from the opening of the lagoon to 200 yards away from the opening of the lagoon. The group that I was in was 150 yards

The purpose of this experiment was to test how fertilizer impacts the growth of microorganisms of Susan’s Swamp, by measuring the amount of microorganisms found in each sample. I was looking for moving microorganisms because it was difficult to distinguish between the fertilizer and the microorganisms. According to Good and Beatty nitrogen is found in fertilizer and when the nitrogen is added to the aquatic ecosystem it will cause a flourishing of microbial growth, which can result in a “dead zone”

We collected water samples from Zoo Miami to determine how much Turbidity and Dissolved Oxygen our samples had. Our water samples were from the Amazon Lake and the Giraffe Enclosure, and we can say that the Giraffe Water is more turbid since the water has excrement and probably urine from the Giraffes. The Amazon Lake has more dissolved oxygen since the lake has a population of fish and probably algae and plankton. II. INTRODUCTION We collected water samples from the Amazon Lake and Giraffe

Area around Te Waihora/Lake Ellesmere has significant negative impacts on water quality. From dairy farming to human activities, the causes of poor water are soaring. As a result, animal controlling, irrigating, and cleaning up are some of the best methods of how to solve the problems. First of all, keeping cows and sheep away from water source is one way to minimize the nitrogen leaching into the groundwater and lake. How luck the Lake Ellesmere is when the surrounding city is not New York or Tokyo

The problem with Lake Erie is that it is infested with this toxic algae making it hard for the people of Toledo to drink it. The causes of the bacteria didn’t start in Toledo. It stated hundreds of miles from Toledo. The algae are fed by natural and commercial fertilizers from the watersheds, farms, livestocks, and city sewers. All of the waste from those sources form in the shallowest part of Lake Erie, and when the water warms the bacteria spreads. Other areas around Lake Erie are already experiencing
