Biochemical Cycles

1. Elements

   • Nitrogen
     • Nitrogen is also found in the nucleus of every living cell as one of the chemical components of DNA.
   • Hydrogen
     • Hydrogen is the chemical element with the symbol H and atomic number 1. With a standard atomic weight of 1.008, hydrogen is the lightest element in the periodic table.
   • Carbon
     • Carbon is a chemical element, like hydrogen, oxygen, lead or any of the others in the periodic table.
   • Phosphorus
     • Phosphorus is a mineral found in many foods. One important function it performs in your body is working with calcium to build strong, healthy bones.

2. Cycles

   • Water cycle
     • The water cycle shows the continuous movement of water within the Earth and atmosphere. It is a complex system that includes many different processes. Liquid water evaporates into water vapor, condenses to form clouds, and precipitates back to earth in the form of rain and snow.
   • Cabron cycle
     • The carbon cycle describes the process in which carbon atoms continually travel from the atmosphere to the Earth and then back into the atmosphere. Since our planet and its atmosphere form a closed environment, the amount of carbon in this system does not change.
   • Phosphorus cycle
     • The phosphorus cycle is the process by which phosphorus moves through the lithosphere, hydrosphere, and biosphere. Phosphorus is essential for plant and animal growth, as well as the health of microbes inhabiting the soil, but is gradually depleted from the soil over time
   • Nitrogen cycle
     • The nitrogen cycle is a repeating cycle of processes during which nitrogen moves through both living and non-living things: the atmosphere, soil, water, plants, animals and bacteria. In order to move through the different parts of the cycle, nitrogen must change forms.
