The Water Cycle
Description: the circulation of water through the atmosphere, how the water goes through evaporation, precipitation, run-off and condensation. Evaporation is the process of liquid becoming a gas. Precipitation is when the water falls from the clouds. Run-off is when the water from a puddle or other hole runs into another body of water. Condensation is the transition of water vapor to a liquid. Also, the factors that affect these stages. Transpiration, where plants absorb the water through their roots, has been affected by this cycle.
The Water Cycle does not have a chemical reaction involved, but instead has a physical property throughout the cycle. It just changes the state that the water is in not the actual properties.
Organic and/or Inorganic components: Organic Compounds: Amino acids, peptides, nucleic acids, and proteins. Inorganic compounds: fertilizer and ammonia these are man made. https://sites.google.com/site/knightrogencycle2013/major-storage-reservoirs
The Carbon Cycle
Description: Carbon is an element that is always on the move. Carbon is a gas that moves all throughout the atmosphere. Carbon dioxide is a greenhouse gas and it is essential to the survival of life. It keeps the heat within the atmosphere; the Earth would be frozen without this. This also contributes to the planet warming; global warming.
The chemical reactions within the Carbon cycle include photosynthesis and metabolism. In photosynthesis, plants use carbon dioxide and produce oxygen. Metabolism does the opposite: it uses oxygen to produce carbon dioxide as a product. http://chemistry.elmhurst.edu/vchembook/306carbon.html
The inorganic and organic compounds within the cycle includes: organic compounds: natural gas (methane), oil, coal, wood. Inorganic compound would be Auto and factory emission, plastics, paper, and cloth (man made)
The Nitrogen Cycle
Description: Nitrogen has DNA, RNA, and proteins; the 3 building blocks of life. There is nitrate, nitrite, and ammonium. The cycle first begins with Nitrogen fixation, N2 is converted to ammonium. Then the cycle continues through denitrification, nitrification, nitrogen mineralization, and nitrogen uptake. Humans have also affected the Nitrogen cycle in many ways. Some ways it has been impacted are the burning of fossil fuels, using fertilizers, and cultivating legumes all fix nitrogen. The majority of the Earth's atmosphere is nitrogen.
The chemical reaction in the Nitrogen cycle would include the different forms of Nitrogen such as: Nitrate( NO3-), Nitrite (N02-), and ammonium (NH4+--->organic N) found in the notes we took in class.
Organic/ Inorganic Compounds: Organic examples would be animals, fungi, amino acids, Inorganic examples would be the man made fertilizer
The Phosphorus Cycle
Description: The phosphorus cycle contains a lot of critical parts to it. Phosphorus is an important chemical for plants and animals. The phosphates are essential to ATP. They're used in the building proteins; which is important to vertebrates. However, this cycle does not have a has phase. The sedimentary rocks contain a high level of phosphorus.
There is no chemical reaction in the phosphorus cycle. It is a physical cycle that deals with plant growth; there are no chemical changes undergoing this process. https://www.sciencelearn.org.nz/resources/961-the-phosphorus-cycle
The inorganic and organic compounds are found in the phosphorus cycle. Some examples of organic compounds would be soil and rock sediments. Inorganic compounds would be combined with P and include: Ca, Mg, Fe, Al, and clay materials. They also include plankton, plants, and weeds. http://karnet.up.wroc.pl/~weber/fosfor2.htm
