The ozone layer which is our protector from the sun is impacted with the increase of burning fossil fuel such as oil, coal, and natural gas which increases atmospheric carbon dioxide. For all plant growth, phosphorus is an important mineral that is used as fertilizers that assist with plant blooming and production. This key element that plants use is needed for animals and humans and it begins with rain runoff that breaks down rocks which release phosphorus into the ground and eventually into the water supply. Humans’ impact the phosphorus cycle by the over use of manmade fertilizers that eventually returns to the earth and find their way into the ocean. With water pollution ocean life becomes tainted with over fertilization that can lead to death of plant and animal life.
Carbon, Phosphorus, and Nitrogen Cycles Diana Cervantes Everest University Abstract In this essay we discuss the Carbon, Phosphorus, and Nitrogen cycle. We discuss what they do, and why they are important. We also discuss how humans impact the cycles. Keywords: Carbon Cycle, Nitrogen cycle, Phosphorus cycle Carbon, Phosphorus, and Nitrogen Cycles The biogeochemical cycle is a cycle that shows how atoms are recycled in the biosphere. Three important cycles in the biogeochemical cycle are the carbon, phosphorus, and nitrogen cycles.
Phosphorus is in the lithosphere of the earth and is found in the rock and soil minerals. Phosphorus is limited in many ecosystems as the rocks break down, which is a slow process, phosphorus is released. Then the plants absorb phosphorus from the soil or water and phosphorus is then passed to the animals of the ecosystem because they feed on the plants. Phosphorus compounds are then broken down and released thru urine and other waste, which is then absorbed by plants and the cycle starts all over again. The main source of nitrogen is in the air.
Jessica Musser Human Impacts on the Carbon, Phosphorus and Nitrogen Cycles October 27, 2012 Professor Amanda Slaughter Environmental Science The carbon cycle is the set of biogeochemical processes by which carbon undergoes chemical reactions, changes form, and moves through different reservoirs on earth, including living organisms. The geological component of the carbon cycle is driven by plate tectonics and includes processes like volcanic eruptions and burial of carbon-rich sediments on the ocean floor. The biological component of the carbon cycle is driven by respiration and photosynthesis by living organisms. Humans affect the carbon cycle in many ways but mostly by burning fossil fuels (coal, oil, natural gas). The burning rate of these fossil fuels is close to 6 gigatons per year.
| | The FACTS-I experiment is testing how elevated CO2 influences tree growth, carbon concentration in soils, and other factors over a ten-year period. | Greenhouse Effect | The greenhouse effect is caused by atmospheric CO2 but is necessary to keep the surface of the Earth at a habitable temperature. | | Increased levels of atmospheric CO2 could cause global warming and significant climatic change. | | Life on Earth is protected from dangerous radiation by a protective layer or ozone molecules present in the atmosphere.
Humans pump carbon dioxide into the atmosphere burn everyday by burning using excessive energy, fossil flue and even by simply breathing we are releasing more and more carbon dioxide. Who are the winners and losers among marine organisms in a more acidic ocean? There are some creatures in the world ocean that may benefit from the higher amount of carbonic acid such as photosynthetic algae and sea grass. Much like plants, both of these organisms breathe in carbon dioxide in order to live. However, there is a larger list of organisms that do not benefit from the carbonic acid in the world ocean.
“Their influence is known as the greenhouse gases, which are carbon dioxide, chlorofluorocarbons, methane, nitrous oxide, ozone, and water vapor”(“American Meteorological Society 2007”). These gases mixes with the sun ultraviolet rays, disburse into the earth atmosphere with harmful results. Carbon dioxide from the burning of fossil fuels is one way the human activities effects the environment. Carbon dioxide from the exhaust of cars in heavily polluted cities, farming machinery such as tractors, and smokestacks of refinery companies are just some of the ways carbon dioxide gases are release into the atmosphere by human contributors. The nitrous oxide gases affect the aquatic ecosystem food web chains, which leads from the smallest phytoplankton up to the largest mammal, which is man.
The Cycling of Matter in Ecosystems Saundra Adams Everest University Online Summarize man’s impact on the carbon, phosphorus, and nitrogen. * Discuss how humans impact each cycle. * Give specific examples of each cycle and how humans impact these cycles. The Carbon Cycle: Reservoir of carbon dioxide (CO2 molecules present in the air). Using photosynthesis and further metabolism, carbon atoms, from CO2 these carbon atoms of the organic molecules make up the plant’s body.
An unnaturally large amount of these “greenhouse gases” are released by human activities like burning fossil fuels, deforestation, and mining. These human activities are responsible for global climate change. It isn’t a result of natural causes. The largest source of greenhouse gases is the burning of fossil fuels. Automobiles and energy production use fossil fuels.
When a human use oil in his/her car, van, or truck, they have a great bid of impact on carbon, because when oil is being burned carbon is released into the atmosphere at a very fast rate, than it is removed. The carbon cycle can be affected when carbon dioxide either when carbon is released into the atmosphere or removed from it. Using natural gas is another way human impact on carbon, for the simple reason, we have to use gas to cook food in our homes and for transportation in our vehicles. Human also has an impact on phosphorus by moving it around and it become runoffs. What I mean by that is like in agriculture, phosphates are from a large amount of fertilizer that are being sprayed by farmer workers, in which they have all these different types of chemicals cause problems to the earth.
