Energy Flow and Nutrient Cycling in the Epipelagic Zone of the Ocean Introduction: “Energy Flow’’ is an environmental process that describes the flow of energy through a food chain and attempts to ascertain the relative importance of various individual component species and feeding relationships within a particular ecosystem. “Energy” itself is defined as the ability to do work: All living plants and animals expend energy in their environment. All three laws of thermodynamics apply,…

A common refrain in 1960 was "Lake Erie is Dead." In the 1960s Lake Erie was terribly polluted. We cleaned it up, but it’s polluted once again. Lake Erie contained increased levels of phosphorus and nitrogen, which contributed to eutrophication, (a process that encourages the development of algal blooms). Since the 1960s Lake Erie has had many problems with algae. Waste water from the sewers also made their way into the lake, as this was happening factories were dumping pollutants into the…

cleveland. Because of these pollutants high levels of Phosphorus and nitrogen. “A common refrain in 1960 was "Lake Erie is Dead.” In 1972, the congress passes the clean water act. Farmers created new farming techniques to get rid of as many chemicals as possible. They did this by modifying and getting rid of any phosphates or nitrates in the chemicals, to make it a lot more safe if it accidentally got into Lake Erie.They god rid of as much phosphorus in the environment as they could. “For…

Every minute, a child dies from a water-related disease; combine that with adult fatalities from the same diseases, and the number skyrockets to more than 840,000 annual deaths (“Water Facts”). These individuals are only a tiny fraction of the 750 million people worldwide without access to clean drinking water, water that is often used to sustain what little agriculture they may be cultivating. This crisis closely interrelates with the worldwide hunger issue, which is so prevalent that 21,000…

has various nutrients that can pollute soil and water Farming practices: Farming practices can add unwanted nutrient pollution from the use of fertilizer and other chemicals. Animal and water waste handling: Animal waste contains nutrients such as phosphorus and nitrogen, which can pollute surrounding waters. Proper handling of waste can help alleviate nutrient concentration. Soil testing for nutrient concentrations: A variety of soil tests will be used…

There are seven types of psoriasis, the most common being Plaque Psoriasis, or psoriasis vulgaris, which is identified as raised, inflamed, red skin covered with silvery, white scales. These patches may itch and burn. This kind of psoriasis can appear anywhere on your body. There is also Pustular Psoriasis which is more uncommon and mostly appears in adults. It is characterized by pus-filled bumps surrounded by inflamed, red skin. Erythrodermic Psoriasis is the least common, but it's very…

Fertilizers have high concentrations of soluble nitrogen and phosphorus compounds, and animal wastes contain high levels of nitrate. The use of fertilizers thus can produce high nitrate (a nitrogen-oxygen compound) and phosphate (a phosphorus-oxygen compound) in natural waters. Nitrate can combine with hemoglobin so that oxygen transport in the body is inhibited. This is a potentially serious threat to infants. Water high in phosphorus can stimulate the growth of organisms such as algae. As the…

1. Planning for changes is difficult due to the natural fluctuation of the great lakes water levels but there are factors that are certain that the levels as well as the region are changing negatively due to climate change (Kahl & Stirratt, n.d.). The water levels of the Great Lakes have declined over the past decades (“Climate Change Indicators: Great Lakes Water Levels and Temperatures”, 2016). Climate change is a change in typical weather that lasts longer than usual (“Climate Change, Health,…

fertilizers to help boost the rate plants grow at and is required for genetic materials; DNA, RNA and amino acids (Crash Course Ecology, 2012). Some of the transformations occurring in the global nitrogen cycle parallel those in the carbon cycle. Phosphorus is stored primarily in soil and is an essential component of adenosine triphosphate (ATP) (University of Minnesota, 2016). Figure 1.3 – The Nitrogen Cycle – (University of Minnesota, 2016) Figure 1.4 – The Phosphorous Cycle – (Reef…

The Atlantic Ocean is the second largest ocean out of the five oceans and stretches east of North and South America to west of Europe and Asia. Its climate consists of ocean currents, which are dependent on the uneven heating of the Earth’s surface and continents/landmasses nearby. Ocean currents transport heat energy within the biosphere, with surface ocean currents warming or cooling the air above them, affecting the land nearby. Surface water is affected by wind currents, while deep ocean…
