The Phosphorus Cycle is representative of the cycle of all biologically important mineral nutrients-those elements that have their origin in the rock and soil minerals of the Lithosphere, such as iron, calcium, and potassium. Humans have a serious intrusion into the Phosphorus Cycle that comes from the use of Phosphorus Cycle that contains fertilizers. Phosphorus is mined all around the world then made into fertilizers, animal feeds, detergents and other products. (Wright & Boorse) The third cycle that Humans impact in the Ecosystem is the Nitrogen Cycle. The Nitrogen Cycle is the process by which Nitrogen is converted between its various chemical forms.
The magma that reached the sea bed due to weakness in the crust cooled quickly and formed a layer of basalt above the sediments (see diagram 1). Other magma intrusions
Once this is completed, a perforating gun is lowered into the well. When fired, the gun will create cracks in the rock (Fischetti , 2010). The gun is then removed and a mixture of water, sand and chemicals is pumped into the well under pressure. The intense pressure forces thousands of cracks to open up in the gas laden rock formations. The natural pressure existing in the well forces the water and chemicals back up the well.
This precipitated water runs off into storage areas and later evaporates into the atmosphere once again. As this is a closed, circular system, we can begin the discussion at any point. It is perhaps clearest to start with the movement of moisture from Earth’s surface into the atmosphere. Zone of saturation, in which all pore spaces in the soil and cracks in the rocks are fully saturated with water. The moisture in the zone is called groundwater; it seeps slowly through the ground following the pull of gravity and guided by rocks structure.
Nitrogen fixing bacteria in the roots of leguminous plants reduce atmospheric nitrogen to ammonium using ATP and reduced NAD. The ammonium ions released into the soil are oxidised by nitrifying bacteria firstly to nitrite, and then to nitrate. This oxidation increases the nitrogen content in the soil which plants can use to produces many useful molecules including amino acids, proteins, DNA and ATP. The formation of these ions forms part of the ecological nitrogen cycle which plays a key role in sustaining life on this planet. Plants are the producers for an ecosystem.
Hydrologic Cycle The elements that combine to make water Hydrogen and oxygen are found in dust, grasses, and other stuff that formed Earth. The molten rock, called magma, which made up early Earth, contains water. Some water escaped from the magma and reaches the Atmosphere. As Earth cooled off, the water was able to settle on the surface and billions of liters later the oceans were formed. (5 points) |Score | | | 2.
Some of runoff enters rivers flowing water towards ocean where water cycle had started. Another cycle which is part of the ecosystem is the nitrogen cycle. All living organisms require a source of nitrogen from which to manufacture proteins, nucleic acids and other nitrogen containing compounds. Plants take up most of nitrogen they need in form of nitrate (NO3- ) ions from the soil. Ammonification is the production of ammonia from organic compounds such as urea.
2013).Pharmaceutical companies sometimes place active chemicals and waste into groundwater sources, in which almost all of the groundwater may be untreated which most likely cause contamination. (Herber, 2002). Abstract: Increase in the emissions of carbon dioxide by burning fossil fuels is the largest cause of environmental down grading resulting not only in global warming but also causing acid rain which alters the pH balance of ground water. Water is a universal solvent; however, its dissolving properties are very sensitive to changes in temperature and pH. Global economic growth has, unfortunately,
Differing forms of oil extraction have exponentially advanced into the world's modern era. The process of fracking, or Hydraulic fracturing is the fracturing of rock by a pressurized liquid. Engineers of this process have extracted oils such as petroleum while digging deep into the Earth's surface the fracturing the Earth into veins or dikes. The commonly used practice is that which involves hydro fracturing, where water is mixed with sand and chemicals is injected at high pressures into the facture which yields petroleum and other substances. This practice is common in the field of shale gas, tight gas, tight oil, and hard rock well extraction.
Large amounts of methane and other poisonous gases released into the air from the gas wells contribute to heavy air pollution and global warming. Fracking has been linked to movement of radioactive materials and heavy metals from the underground layers of the earth to the surface through flow-back
