Cycle Of Phosphorus Research Paper

Human impact on the cycling matter in ecosystems can change a lot of things. Humans can either help or hurt things. The carbon, nitrogen and phosphorus cycles are the three cycles of matter in ecosystems. What are these cycles? How do humans effect each one of these individual cycles? What are some examples of humans effecting these cycles?

Inorganic ions include those of sodium, phosphorus and hydrogen. Describe how these and other inorganic ions are used in living organisms.

Photosynthesis is a vital process that requires to utilize energy for plants. This experiment was done to evaluate the effects of carbon availability on photosynthetic activity. The aquatic plant Elodea densa was placed into sodium bicarbonate solutions of five concentrations ranging from 0.1% to 1.0%, in five independent trials (excluding the negative control treatment of water). The temperature and light intensity was constant. The results indicated a directly proportional relationship between the availability of carbon dioxide and the rate of photosynthesis of Elodea Densa, as photosynthesis continued to increase with increasing amounts of bicarbonate. The most O2 amount of oxygen produced was with the 0.7% NaHCO3 concentration and least with the control of water. The null hypothesis that stated carbon concentration does not affect rate of photosynthesis of the aquatic plant was rejected. The predicted hypothesis that an increase in bicarbonate concentrations results in an increase in the photosynthetic rate was accepted. In conclusion, there is a significant increase in photosynthetic activity as the concentration of NaHCO3 increases.

About 75% of the minerals are found in bones and teeth as calcium and phosphorus and their concentrations are generally regulated by homeostatic mechanisms.

According to our biology book, “there are several elements (water, oxygen, carbon, nitrogen, phosphorus) that cycle through our world just like energy is cycled. These elements are never created or destroyed, but instead they are constantly recycled and reused.” Various human activities can hamper/benefit these cycles. Two of the cycles and how they are benefited and adversely affected by human activities are explained below.

What is Phosphorus, and How is it Extracted Phosphorus is a non-metal solid, with atomic number 15, and usually comes in white, red, or black allotropic forms. It is found in phosphates, particularly apatite, which is the most common in Florida. These phosphates lie anywhere from 15-50 feet under the ground, and are only accessible by removing the topsoil in a

Eutrophication, a term that derives from two greek words, eu, meaning “good,” and trophic, meaning nutrition or nourishment, is the enrichment of water bodies with nutrients like nitrogen and phosphorous that stimulate plant growth. Nitrogen is often found in rocks, soils, organisms, and the atmosphere; phosphorous resides mostly in rocks/soils and organisms. Having nitrogen and phosphorus in the ecosystem isn 't necessarily a bad thing, in fact, it 's required. Nitrogen is needed for the production of proteins and amnio acids, while phosphorous is required for the synthesis of DNA and RNA, and is involved in energy transfers. (Danver & Burch, 2011) However, too much of a good thing, can be a bad thing.

Based on the notes we took in class, the activities we did, and the Journey of X, X is Phosphorus. Phosphorus is a chemical element. In the journey of X, X spent the majority of the journey, in soil, or surface water. The abiotic reservoirs for the phosphorous cycle are soil and surface water. This alone eliminates the water and carbon cycle because they don't have soil as there abiotic reservoirs. Nitrogen is in the atmosphere, and phosphorus is not found in the atmosphere. Throughout the whole journey of X, X was never in the atmosphere. That means it is not Nitrogen. This clearly shows how X is phosphorous.

The next macronutrient is phosphorus. Two most common forms of phosphorus are white phosphorus, made up of phosphorus atoms and arranged like a tetrahedron, and red phosphorus which is a non-crystalline but solid form of the element. Another form is black phosphorus, where it comes from the arrangement of the atoms in the form of a ring structure and looks similarly like the graphite (Stephanie, 2015). However, this element is never considered as a free element on Earth due to its high reactivity. The presence of P in the plants help the normal growth and maturity of the plants. According to Busman and his friends (2002), one of the main roles of P in living organisms is in the transfer of energy. Organic compounds are used P to transfer energy

If we look at the figures above we could see that the experiment phosphorus of green algae, cyanobacteria and diatoms, when the phosphorus was doubled had higher values than the baseline when nutrient input was the same. When we look at the growth rate of green algae (Figure 1), the baseline phosphorus and the experiment phosphorus did not differ much, same with the baseline phosphorus and experiment phosphorus for the carrying capacity of diatoms (Figure 6).

Web. 23 Dec. 2015)The boiling point for Phosphorus is 280.50 degrees Celsius. While the melting period is 44.20 degrees Celsius. Phosphorus has both electrical and thermal conductivity that goes for both red and white. Phosphorus has a density of 1.82 grams per cubic centimeters and a low hardness.The abundance of phosphorus in the Earth's crust is estimated to be 0.12 percent, making it the 11th most common element. Important man-made source from Phosphorus is fertilizer used for farming or in your garden/flowerbeds ("The Nature of Phosphorus in Soils." : Nitrogen : University of Minnesota Extension. Web. 23 Dec. 2015. )This is important to the agriculture industry even though a lot of the use cow manure it still deals with Phosphorus. When dealing with chemical properties white Phosphorus has more to do with the reaction due to the fact it can spontaneously ignite. It is

This lab was called photosynthesis: understanding photosynthesis. It is a highly complex process that needs to be broken down in many steps to understand how it works. This lab covers the big components in photosynthesis including carbon dioxide intake, light consumption, and varying pigmentation.

Without photosynthesis we would not be able to receive energy. We should be more appreciate of plants, without them we would not survive. This paper will explain the basic components require for photosynthesis, the role of chlorophyll, how energy is transferred, and photosystems I and II and the most precious product results of photosynthesis.

     Photosynthesis is a biochemical process in which plant, algae, and some bacteria harness the energy of light to produce food. Nearly all living things depend on energy produced from photosynthesis for their nourishment, making it vital to life on Earth. It is also responsible for producing the oxygen that makes up a large portion of the Earth¡¦s atmosphere. Factors that affect photosynthesis are light intensity and wave length, carbon dioxide concentration, and temperature.
