Biochemical Cycle Tre'von Gore

the water cycle

the water cycle is just the migrations of water from the sky to the ground and then back to the sky

in the water cycle there aren't any chemical reactions that occurs during the water cycle there is only a physical change.
  • Photosynthesis: when plants synthesize organic compounds from CO2 and H2O using light energy.
  • the ground and ocean are the inorganic compounds that hold the water throughout the cycle.

Human intervention- Water pollution is also caused by humans in many ways, including smog and improper waste disposal. When acid rain occurs it is very evident that our pollution affects the water cycle. By conserving and taking care of the water you have.

Carbon Cycle
the carbon cycle is the process when carbon components are into living organisms and then go back to the atmosphere by breathing, decaying, and burning of fossil fuels.

Chemical Reactions: two main processes which occur: photosynthesis and metabolism. During photosynthesis, plants use carbon dioxide and produce oxygen. During metabolism oxygen is used and carbon dioxide is a product.

Organic and Inorganic components:

  • Atmosphere
  • Terrestrial Biosphere (usually includes freshwater systems and non-living organic material, such as soil carbon)
  • Oceans (includes dissolved inorganic carbon)
  • Sediments (includes fossil fuels)

Human Intervention: Humans impact the carbon cycle during the combustion of any type of fossil fuel, which may include oil, or natural gas. Humans intervene during the carbon cycle by burning fossil fuels.

the nitrogen cycle
the nitrogen cycle is when the nitrogen compounds are going through the environment and living organisms by nitrogen fixation and decomposition.

Chemical Reaction:

  • Nitrogen uptake - NH4+ → Organic N
  • Nitrogen mineralization - Organic N → NH4+
  • Nitrification - NH4+ → NO3-
  • Denitrification -
  • NO3- → N2+ N2O
  • NO3- → NO2- → NO → N2O → N2.

Organic and Inorganic: nitrogen is organic through the first stages of the cycle and turns into inorganic at the end of the cycle

Human intervention: the use of synthetic nitrogen fertilizers

the phosphorous cycle
Phosphorus compounds goes in a circle through rocks, water, soil and sediments and organisms.

chemical reaction: Over time, rain and weathering cause rocks to release phosphate ions and other minerals.

organic and inorganic: This inorganic phosphate is then distributed in soils and water. Plants take up inorganic phosphate from the soil.

Human intervention: the cutting of tropical rain forests and through the use of agricultural fertilizers.
