SVN 3m: The Nitrogen Cycle

568 Words3 Pages

SVN 3M The Nitrogen Cycle Name: Isabelle Rowe
Go to the following website: http://nortonbooks.com/college/biology/animations/ch38a02.htm
1. What are the 2 forms of usable nitrogen?

The two forms of usable of nitrogen are ammonium and nitrates.

2. What is the term used for this conversion process?

This conversion of N2 (nitrogen) into NH4+ (ammonium) and NO3- (nitrate) is called nitrogen fixation.

3. Much of nitrogen fixation by humans is done by what?

Most of nitrogen fixation done by humans is the result of industrial production of fertilizers.

4. How is nitrogen returned back to the atmosphere?

Nitrogen is returned back into the atmosphere through denitrification, which is done by soil bacteria.

5. Do the quiz at the …show more content…

What do nitrifying bacteria do?

The nitrifying bacteria turn nitrogen into usable nitrates, which the plants can take up.

2. Explain the process of ammonification.

Bacteria convert nitrogen gases into ammonium, which allows nitration to turn ammonium into nitrates.

1. Why is nitrogen such a critical nutrient?
Nitrogen is important for the growth. It helps create amino acids, DNA, and proteins.
2. How is some of this nitrate converted by to nitrogen?
The conversion of nitrates into nitrogen is called denitrification.

1. How can excess nitrates from fertilizers be a problem for the environment?
The nitrate gets into the runoff, which leads to overgrowth of algae and aquatic plants in pounds, lakes, and oceans.

Nt1310 Unit 2 Term Paper

442 Words | 2 Pages

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).

Summary Of What's Eat America By Micheal Pollan

387 Words | 2 Pages

In “What’s Eating America,” Micheal Pollan criticizes America’s dependence on fossil fuel and fixed nitrogen instead of organic farming. In 1947, a munition plant used explosives to make chemical fertilizers. After WWII, the surplus of ammonium nitrate are converted into agricultural purposes. Although the earth’s atmosphere consists of 80% nitrogen, almost all the atoms are useless. In 1909, Fritz Haber discovered a way to fix nitrogen molecules by using electrical lightning.

Eutrophication, which is excessive richness of nutrients in any form of body of water, frequently due to runoff from the land, which causes a dense growth of plant life and death of animal life from lack of oxygen, is another reason why the creek could be polluted. Fertilizers are used in farming to provide crops with nutrients, but they also play a big role in the Eutrophication process. If too much fertilizer is used, it leaches from the soil in

Environmental Science and Sustainability (SCI201 -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.

Conodoguinet Creek Field Observation Report

842 Words | 4 Pages

Eutrophication is the excessive nutrients in a lake or body of water, frequently due to runoff from the land, which causes a dense growth of a plant life and death of animal life from lack of oxygen. We tested for phosphate, nitrate, and dissolved oxygen. Phosphates and Nitrates are found in fertilizers, laundry detergents, and sewage treatments. Dissolved oxygen is microscopic bubbles of gaseous oxygen that are mixed in water and aailable to aquatic organisms for respiration. We found that there was a phosphate average of 0.1 parts per million (ppm).

Biology: Photosynthesis And Respiration

593 Words | 3 Pages

All organisms use food molecules, like glucose to produce ATP. The production of ATP occurs during cellular respiration. ATP provides the cells with energy that is necessary to produce oxygen. The seeds/plants are autotrophic organisms, which produce their food from the energy that the light provides them. To release the stored energy within the food molecules, the germinated seeds carry out respiration and the release of carbon dioxide.

Haw River Case Study

Farmers turned to fertilizer, which contains Nitrates. Nitrates also known, as NO3 is a natural compound made of oxygen and nitrogen (Chern, 1999). Nitrates can be found in the air, soil, water, and plants (Johns & Yaremcio, 2004). Much of the nitrate in our environment comes from decomposition of plants and animal wastes (Partnership For Environmental Education and Rural Health, 2015).

Compare And Contrast Cellular Respiration And Photosynthesis

420 Words | 2 Pages

The stomata are the most critical piece to this process, as this is where CO2 enters and can be stored, and where water and O2 exit. Cellular respiration also known as oxidative metabolism is important to convert biochemical energy from nutrients in the cells of living organisms to useful energy known as adenosine triphosphate (ATP). Without cellular respiration living organisms would not be able to sustain life. This process is done by cells exchanging gases within its surroundings to create adenosine triphosphate commonly known as ADT, which is used by the cells as a source of energy. This process is done through numerous reactions; an example is metabolic pathway.

Coalbed Methane Synthesis Lab Report

763 Words | 4 Pages

Lab research has shown that essentially all methane sorbed on coal can be stripped by nitrogen without necessarily reducing the total system pressure. That is, methane desorption from coal is achieved by reducing the partial pressure of methane rather than merely the total pressure of methane rather than merely the total pressure. Lab and modeling results are presented to pressure. Lab and modeling results are presented to demonstrate how nitrogen injection in coal can accelerate methane production rates and enhance reserves. Scoping process economics of enhanced coalbed methane production also appear to be attractive.

Explain How To Prevent A Dog's Urine From Killing Grass Essay

1051 Words | 5 Pages

You should only really fertilize your lawn about four times a year. That will not always be enough to stop the urine from killing the grass. You could try planting a new species that is more resistant to the nitrogen, for example you could plant rye grass or fescue grass if you do not already have the grass. Some other things that will dilute the nitrogen in the pee are apple cider vinegar and tomato juice can dilute the pH levels in the pee. Other organic foods and liquids are usually good for diluting the nitrogen.

Nitrogen In The Haber Process

1161 Words | 5 Pages

Without the presence of the element the Haber Process simply could not exist. In the equation for ammonia one mole of N2 is needed for every three moles of H2 (Crash Course; 2013). Ammonia needs nitrogen to become ammonia. This means that the global food product would largely decrease if nitrogen was not used in the process. Nitrogen is created through fractional distillation.

Cause Of Environmental Degradation

734 Words | 3 Pages

Nowadays, environmental degradation has become an important issue. This is because environmental degradation is one of the largest threats that is being looked at in the world today. This is because of the depletion of important resources such as air, water, and soil; the destruction of ecosystems; habitat destruction; the extinction of wildlife; and pollution. To limit the impact of these situations, it is important to know the possible side-effects of environmental degradation. Therefore, there are several causes and negative effects of environmental degradation provided in this essay with some recommendations to prevent it.
