Carrie Grishom Environmental Science 07/24/2012 In this essay, I am going to talk about how the biochemical cycles in the ecosystems, and collar key elements heavily affected by human activities: vitamin C, phosphorus, and nitrogen. What is ampere-second? Carbon is a widely distributed element that forms organic compounds in combination with hydrogen, oxygen, etc., and that occurs in a pure state as diamond and graphite, and in an impure state as charcoal. emblematic representation: C; atomic weight: 12.011; atomic act: 6; specific gravity:  (of diamond) 3.51 at 20°C; (of graphite) 2.26 at 20°C. (Dictionary.com, LLC, 2012) The century cycle is a typeset of biogeochemical forge which means light speed undergoes chemical reactions, it moves by different reservoirs on earth including living organisms, like humans. matchless of the geological chemical element of the coke cycle is process through is volcanic eruptions and sediments on the ocean floor. The human melt down influenced the global cycle in different ways, such(prenominal) as burning dodo fuel. Carbon is essential to life on earth for structure, energy and in case of humans. The human activities such as burning fossil fuels has accelerated and has contributed to long termination rises in the atmosphere.

When humans burn down oil it releases carbon into the atmosphere causing an imbalance, making carbon dioxide concentrations to increase. In addition, unclutter forests, we reduce the ability of photosynthesis to remove carbon from the atmosphere. Phosphorus is a solid, nonmetallic element existing in at to the lowest degree three allotropic forms,! one(a) that is yellow, poisonous, flammable, and bright in the dark, one that is red, less poisonous, and less flammable, and another that is black, indissoluble in or so solvents, and the least flammable. The element is used in forming smoke screens, its compounds be used in matches and phosphate fertilizers, and it is a necessary ingredient of plant and animal life in bones, nerves, and embryos. Symbol: P; atomic weight: 30.974;...If you want to overreach a just essay, order it on our website: OrderCustomPaper.com
