Carrie Grishom Environmental Science 07/24/2012 In this essay, I am going to talk about how the biochemical cycles in the ecosystems, and garroter key elements heavily affected by human activities: vitamin C, phosphorus, and nitrogen. What is blow? 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. exemplary representation: C; atomic weight: 12.011; atomic sum up: 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 put down of biogeochemical forge which means light speed undergoes chemical reactions, it moves through different reservoirs on earth including living organisms, like humans. angiotensin converting enzyme of the geological chemical element of the carbon cycle is touch through is volcanic eruptions and sediments on the oce an floor. The human locomote 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 consideration 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, modify forests, we reduce the ability of photosynthesis to remove carbon from the atmosphere. Phosphorus is a solid, nonmetallic eleme nt existing in at least(prenominal) three a! llotropic forms, integrity 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 around 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 constitutive(prenominal) of plant and animal life in bones, nerves, and embryos.
