Phosphorus Cycle Essay

1458 words - 6 pages

Question: Phosphorus cycles extremely slowly through ecosystems due to the afct that the major reserviors of this nutrient are contained largely in rock and other substrates. As a consequence, this nutrient often limits primary productionDiscuss this statement in term sof the global phosphorus cycle, and outline the general patterns of the cycle. What human activities are considered to impact upon the phosphorus cycle?Answer:IntroductionIn the ecosystems, nutrients continuously cycle through living-organisms and non-living environments in such a way that all organisms can access nutrients to maintain their growth. Phosphorus is one of the most essential nutrients to organisms. Phosphorus has an extremely slow cycle due to the fact that large quantity of this nutrient is stored in sedimentary rocks for considerable period. As a result, this nutrient often limits the primary production. In order to improve crop production, humans have tried to increase the phosphorus concentration in soils by adding phosphorus-based fertilisers and manures to agricultural lands. However, the excessive use of such fertilisers in agricultural lands and improper waste discharge into aquatic ecosystem lead to nutrient pollution in theImportance of PhosphorusPhosphorus is the essential element to fauna and flora in any ecosystem. Like nitrogen, it enhances major processes in plants such as photosynthesis, flowering, maturation, fruiting and seed production. In addition, phosphorus also stimulates root growth, strengthens structural tissues in straw or stalks and improves crop quality, especially in forages and vegetables (Brad& Weil 1999). Phosphorus is also the common element in structure of living organisms. According to Enger and Smith (1998), this element is present in many important biological molecules such as DNA and in membrane structure of cells. The bone and teeth of animals also contain significant quantities of phosphorus. Therefore, animals including human beings need to consume the phosphorus-contained food to survive.The phosphorus deficiency severely affects the growth of plants and animals. In the absence of adequate amount of the element, plants suffer from an abnormal growth such as unsatisfactory development of root, yellowing and sentence of leaves, thin stemmed and stunned trees, discoloration of stem and leaves (Brad & Weil 1999). In addition, the phosphorus deficient plants become less productive in term of quantity and quality. Similarly, if animals do not have adequate phosphorus consumption, they usually become dwarfed and weak. Bear (1963) shows that the livestock grazed only in located areas often develop the phosphorus deficiency symptoms, for instance, their joints tend to stiffer, their skins lose their velvety feeling, they fail to shed their hair properly, and they also have abnormal appetites for bones.Phosphorus CyclePhosphorus cycles through sedimentary rocks, water and living organisms (see figure 1). Since phosphorus is...

Considerations for the Genetic Modificaiton of Wheat

2233 words - 9 pages . Modified wheat does not require large amounts of herbicides and fertilizers this means that there will be less contamination of water ways, lakes and dams. The GM does not require much fertilizer so there will be a much smaller impact on phosphorus supplies meaning that they will be more sustainable for future years. That is why I have chosen to test the latest genetically modified wheat that had been developed.   Carbon Cycle The

Each of the 4 biogeochemical cycles recycles all of the important elements required to sustain life back by cycling back though the earth for reuse. In the Phosphorus Cycle plants, producers, absorb inorganic phosphate from the soil. When animals, secondary consumers, like the Olive Baboon consume plants, they acquire the phosphorus that was present in the plant that was absorbed from

Such rivers are commonly known as sensitive rivers. These nutrients excite the production of algae providing food for their growth under the accurate circumstances thus causing

1090 words - 5 pages that are normally found naturally in crop’s soil. Many people think that using chemical fertilizer will replenish the lost nutrients, but the fertilizer only replenishes nitrogen, potassium, and phosphorus. A lot of times, phosphorus is drained from the soil into groundwater. Phosphorus does not dissolve in water, causing water contamination to many water resources. It could hurt both crops and humans. The phosphorus can also cause soil to harden

Seeing as how every living being is a complex collection of chemicals, it almost goes without saying that a chemical cycle would be extremely important. “The most important biogeochemical cycles affecting ecosystem health are the water, carbon, nitrogen, and phosphorus cycles” (Anennburg Learner, 2010). Water is the most obvious of the chemicals that are important to an ecological
