Carbon, Phosphorus And Nitrogen Cycles Essay

708 words - 3 pages

Humans are undoubtedly one of the largest consumers on the planet and without a doubt use and effect a greater portion of the world’s supply of natural resources than any other species. Most likely it is because of the large size of the species, or perhaps it is the result of over-consumption. There are three biogeochemical cycles that humans effect daily: The Carbon Cycle, The Phosphorus Cycle as well as the Nitrogen Cycle. As learned by the Law of Conservation of Matter, atoms simply cannot be destroyed or created, instead they recycle themselves, so these cycles indicate how the unique variations of atoms are converted and used by consumption.
Carbon is found in the World’s atmosphere, ...view middle of the document...

The cycle begins with rain runoff that breaks down rocks which unleash phosphorus into the ground and finally into the water supply. From that point, the phosphorus is drawn in from vegetation after which are changed into an organic phosphate that is eaten by consumers. Like carbon the majority of the recycling at this stage takes place when the animal excretes the phosphorus back into the land simply by sweat, urine and then potential death. Humans are impacting on this cycle with the over usage of fertilizers loaded with phosphorus which are definitely finding their way into the ocean, whereby the excess is wreaking destruction on the ecosystems. With a lot of phosphorus getting contained primarily in the ocean, ocean life starts to become tainted with over fertilization which can be responsible for the death of plant and animal life.
Nitrogen is available in huge volumes in our atmosphere and like phosphorus, can be used by most of the organic substance to continue living. Just like the cycles before, the Nitrogen cycle will start by...
