Biogeochemical Cycles Chapter 3 of your textbook describes five biogeochemical cycles (also called nutrient cycles) which carry elements and compounds essential to life on earth: the hydrologic cycle, the carbon cycle, the nitrogen cycle, the phosphorous cycle and the sulfur cycle. Read the section in the textbook (3-4) and study the figures (3-14 through 3-18). These cycles are constantly going on around us. Think about how we are involved in these cycles. What parts of the major biogeochemical cycles do we witness or experience in our daily lives? Give one example per post or response. Think about where the nutrient may have come from or where it may go next and whether the process may have been affected by humans. A simple example: Yesterday I was at the beach and witnessed in raining into the ocean. This is part of the hydrologic cycle. Most of the rainwater probably came from evaporation of water from the ocean and most of it will either evaporate again or remain in the ocean for a long time. This is a natural process O Type here to searchExplanation / Answer
The water cycle, nitrogen cycle, carbon cycle, sulfur cycle and phosphorus cycle they all are going around us touching our lives in every second. For example the oxgen we are breathing right now is prepared by plants by the process of photosynthesis in which carbondioxide gets converted into oxygen in the presence of sunlight. Apart from this the carbon which is present in all fossil fuels is because of the the conversion of soft and hard parts of plants and animal which contain cellose rich in carbon
The potable water which we are drinking is because of the evaporation of salt water from the ocean and then condensation of this vapour will take place to give us fresh water in the form of rain.
The food after digestion is excreated and when left for anarobic degradtion it will give nitrogen rich manure used by plants to assist it's growth.
The burning of coal, natural gas, and any other fossil fuels increased the amount of Sulphur in the atmosphere and ocean and while depleting the sedimentary rock's sink. Without the intervension of human being this sulfur would stay in rocks for millions of years until it was uplifted through tectonic events and then released through erosion and weathering processes. Instead it is being drilled, pumped and burned at a steadily increasing rate.
Humans beings have greatly influenced the phosphorus cycle by doing processes mining phosphorus, converting it into fertilizer, and by shipping fertilizer and products from one city to another. Transporting phosphorus in food from farms to cities has made a major change in the global Phosphorus cycle. Human interference in the phosphorus cycle occurs by overuse or careless use of phosphorus fertilizers. This results in increased amounts of phosphorus as pollutants in bodies of water resulting in eutrophication. Eutrophication devastates water ecosystems by inducing anoxic conditions.
