We are diverting or removing 40% of the photosynthetic effect of and plants. By burn fossil fuel has increased atmospheric CO2 by 35 %. ( Pearson Education, Inc. 2011) Also deforestation and soil degradation release significant amounts of CO2 to the atmosphere. (Wright, Boorse 2011) Phosphorus Cycle- The phosphorus cycle is the biogeochemical cycle that describes the movement of phosphorus through the lithosphere, hydrosphere, and biosphere. Unlike many other biogeochemical cycles, the atmosphere does not play a significant role in the movement of phosphorus, because phosphorus and phosphorus-based compounds are usually solids at the typical ranges of temperature and pressure found on Earth.
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.
Human’s impacts the nitrogen by their crops from using fertilizers which damage the root’s and cause bacteria. Reference Google Environmental Science Richard T. Wright Dorothy F.
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.
Lab 4 – Energy Sources and Alternative Energy Experiment 1: The Effects of Coal Mining Table 1: pH of Water Samples | Water Sample | Initial pH | Final pH (24-48 hours) | Pyrite | 4.5 | 5 | Activated Carbon | 4.5 | 6.5 | Water | 4.5 | 4.5 | POST LAB QUESTIONS 1. Develop hypotheses predicting the effect of pyrite and coal on the acidity of water? a. Pyrite hypothesis = Adding pyrite to water it will cause the pH levels to increase. b. Coal hypothesis = If I add activated carbon to the water it will lower the pH level of the water.
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. The coal is burned which boils the water. The water becomes steam, which turns the turbine, activating the generator, then producing the electricity. Because water can also exist as a vapor it can be stored into the atmosphere and be delivered as rain across the planet. Water makes up 90% of the earth’s atmosphere and the other 20% is land Our bodies are about 60 percent water [source: Mayo Clinic].
Eventually, all that is left of the acetyl coenzyme A molecules is carbon, which combines with the oxygen to from carbon dioxide that is emitted as a waste product. The acid cycle creates four molecules of ATP. Lastly the electron transport chain, the NADH that has been created in the previous stages of cellular respiration releases the electrons into the electron transport chain. Each successive molecule in the chain
In respiration, the energy stored in organic compounds may have been produced by the cell itself or stolen from another organism. Respiration uses oxygen from the environment to create carbon dioxide. To obtain energy needed for life, organisms depend on the processes of cellular respiration and photosynthesis. Though they share the same function of changing energy from one form to another, there are many differences between cellular respiration and photosynthesis in regard to the input and output molecules, energetics, cellular location, and ecological importance. Photosynthesis is the process by which plants, some bacteria, and some protistans use the energy from sunlight to produce sugar, which cellular respiration converts into ATP, the "fuel" used by all living things.
Describe how this nonrenewable resource was initially formed. Coal is known often as a fossil fuel. It comes from the original way in which it was formed. Coal is formed when plants and animals die and decay. They are the converted into a carbon dioxide, water and other products that absorb into the environment.
Essay: Carbon dioxide in organisms and ecosystems. An outline of what would have been the plan for an excellent essay is below. It is not prescriptive – there would be other good things to include and other equally good ways of structuring your answer. Brief Introduction: - Though carbon dioxide makes up only 0.04% of the atmosphere, it has many very important roles in organisms and ecosystems. Photosynthesis: - Outline what photosynthesis is/why autotrophs do it - Describe how carbon dioxide is used in photosynthesis.
