Nitrogen fixation can be split into three ways 1. Atmospheric 2. Industrial 3. Biological
 * __Nitrogen Cycle__**

Legume- a type of plant that have a symbiosis (close relationship) with bacteria that fix the nitrogen to be ammonia in their roots. ex:/ Peanuts, soybeans, and alfalfa

Phosphate Cycle__==

==Phosphate is mostly found in rocks, in order for phosphate to cycle, the rocks begin to weather and dissolve into the soil water, these dissolved particles become runoff material and go into the ocean and turn into ocean sediments. After many years the ocean sediments uplift over time and become rock once again. Industries tend to mine large quantities of the phosphate rock which causes the resource to deplete==

==***Phosphate is the only cycle out of the three that does not have the any of the atmosphere involved.

__Carbon Cycle__

The Carbon Cycle along with the Nitrogen cycle has the atmosphere element included in its cycle. The plants and ocean creatures like plankton, absorb the** CO2 **from the atmosphere (photosynthesis) and from there the animals eat the plants and plankton, these animals obtain the** CO2 **and eventually die and decompose, letting out the** CO2 **in the soil. These eventually becomes runoff sedimentation and goes into the ocean. Although the envionment is involved in the Carbon cycle, people are able to contribute as well. Combustion is a resource of** CO2**, things like Deforestation let out a lot of** CO2 **because the tree and plants holding the** CO2 **are burned and release all of what they store. Also combustion from fossil fuels is very important to the distribution of** CO2 **in the atmosphere.

Combustion and photosynthesis would probably be the two processes aht could differ through human activity. For combustion, people are able to regulate the amount of** CO2 **they release. As for photosynthesis, the carbon is being released through deforestation. Also the photosynthesis in the ocean is changing because the plankton are dying due to the ocean heating um from global warming.**==
