For instance Carbon Dioxide from the atmosphere is synthesized by plants, which is ingested and metabolized by animals, which is converted to Carbon Dioxide during respiration and decay. Humans remove over 40% of the photosynthetic that effort plants in order to support human enterprises. When humans burn fossils fuels that increases the atmosphere Carbon Dioxide by 35%, then during the combustion stage the present of air (oxygen), Carbon Dioxide and water molecules are release into the atmosphere. Human has an impact on the Phosphorus Cycle as well as the Carbon Cycle. 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.
The last stage is denitrification where nitrates in the soil are converted into nitrogen gas by denitrifying bacteria that use the nitrates in the soil to carry out respiration and produce nitrogen gas. This happens in anaerobic conditions. Another ecological cycle is the carbon cycle - all organisms need carbon to make essential compounds. Plants absorb carbon in the form of CO2 during photosynthesis and this carbon becomes part of the plant biomass in their tissues. Carbon is passed onto the primary consumers when they eat the plant, secondary and tertiary consumers obtain the carbon source when they eat other consumers.
The carbon cycle is a process that transfers carbon among producers, organisms, and consumers to indicate two particular places it comes from and its oceans and the combustion of fossil fuels, which releases CO2 to the atmosphere. Humans are putting a huge impact on the carbon cycle. Humans are expanding business and housing developments and in the process are chopping down timbers and removing plants which releases significant amounts of CO2 to the atmosphere. The Phosphorus cycle represents the cycles of all the biologically important mineral nutrients. Phosphate comes from a rock that gradually breaks down and will release other ions.
Some of the dissolved carbon dioxide remains in the water, the warmer the water the less carbon dioxide remains in the water. Some carbon dioxide is used by algae and phytoplankton through the process of photosynthesis. In the natural carbon cycle, there are two main processes which occur: * Photosynthesis = plants use carbon dioxide and produce oxygen. * Metabolism = oxygen is used and carbon dioxide is a product Humans impact the carbon cycle during the combustion of any type of fossil fuel, which may include oil, coal, or natural gas. Fossil Fuels were formed very long ago from plant or animal remains that were buried, compressed, and transformed into oil, coal, or natural gas.
There is another type of organism that cleans up after the others, and they are called detritivores. Detritivores (or decomposers) use energy from waste or dead organisms, and they complete the cycle by returning nutrients back into the soil or carbon dioxide to the air. The number of trophic levels is limited by the amount of energy available, which is always set. Trophic levels can include tertiary consumers, quaternary consumers, and so on until there is no longer any more energy available for the biggest and neediest consumers. Energy starts from the resource, which would be the sun in almost all cases.
Plants are the producers for an ecosystem. They photosynthesise carbon dioxide and water and produce energy in the form of carbohydrates and other molecules. Photosynthesis requires water, and plants gain water from the soil using mineral ions such as nitrate produced by the nitrifying bacteria. Hydrolysis of ATP releases energy for processes such as active transport of the nitrate ions (and others such as potassium etc) from the soil into root hair cells, a process that lowers water potential and is used to draw water into the plant from the soil. In leaves, photosynthesis involves the photolysis of water, a process that involves the attachment of two electrons to a magnesium ion in chlorophyll and the production of hydrogen ions from the breakdown of water.
Water also controls our climate weathers. Warm body of water is evaporated, causing high level of wind intensity. For example, the southeastern coast of the US is annually pummeled by hurricanes and tropic storms. Although we would rather live without them, it is a way of balancing the atmosphere. Water is used in photosynthesis by plants, which produce oxygen - this reaction is vital for the earth as the oxygen produced is used by humans to breath Water is used in coal powered electricity stations.
All those examples are able to reduce pollution with those easy ideas we can help the environment. In the future I hope they come up with electric cars or maybe even a water powered engine. Another reason for Global warming is Garbage. The things that we put in the garbage take a long time to compose and can release toxic fumes into the air. We already solved some of the problem by recycling and composting but there’s still a huge amount of garbage.
Owing to the development of industry and the use of fossil fuels, the amount of carbon dioxide in the earth’s atmosphere has produced and the average global temperature seems to have risen. What’s more, deforestation can affect climate changes. The growing of trees and plants can absorb carbon dioxide from the atmosphere because of photosynthesis, however, deforestation lead to carbon dioxide emissions. Both of these can lead to global warming of the atmosphere. The report (UNEPWMO, 2004, P10) also pointed out, the burning of fossil fuels and deforestation are altering the composition of the atmosphere and contributing to climate change.
Moreover test flights have been performed by Czech aircraft which was fully powered with biodiesel. Biodiesel has a large environmental impact; biodiesel reduces the emissions of harmful air pollution, which causes different diseases such as asthma. Biodiesel also reduces the amount of CO2 emission and other greenhouse gases which cause acid rain. In addition the lubricating property of biodiesel may lengthen the lifetime of engines of the cars. People also now use biodiesel for heat; in some areas biodiesel is now cheaper than the other diesel so people try to buy biodiesel for transportation and heating.
