| 13860413095 | Carbon Cycle | Carbon is one of the most crucial elements for life on Earth. All life is carbon based that is currently living on Earth. All organisms require this to survive. Carbon moves throughout the environment with the carbon cycle so that it is dispersed to all organisms and the atmosphere. |  | 0 |
| 13860413096 | Nitrogen Cycle | Nitrogen is another very crucial element to the survival of organisms on Earth. It is needed with the growth of plants and 78% of the atmosphere is made of nitrogen. Nitrogen is very important in making fertilizer for plants. |  | 1 |
| 13860413097 | Water Cycle | Water is the cornerstone all environments on Earth. Every organism requires water. Water has the ability to shift between liquid, gas, and a solid and through this water creates all weather and climate on Earth. |  | 2 |
| 13860413098 | Phosphorus Cycle | Phosphorus is a very important element to organisms. It is used in the creation of nucleotides along with ATP. These two components are essential for organisms. It is also very helpful to marine life in oceans and fresh water locations. However too much phosporus can be deadly to marine life which is why the cycle keeps it at a median. Phosphorus is not common in the atmosphere. There are trace amounts of phosphoric gas but serves no major purpose. |  | 3 |
| 13860413099 | Sulfur Cycle | Sulfur is a key component of proteins. It is common in amino acids and is therefor needed in all plants and animals. Sulfur is also used in the creation of body fluids and bone. |  | 4 |
