How are the carbon cycle an d the nitrogen cycle connected

Nitrogen makes up 78% of the Earth's atmosphere. Nitrogen gas is converted into ammonia by a process known as nitrogen fixation. The Nitrogen Cycle uses excretion to make NH3 (ammonia) Important processes in the carbon cycle are photosynthesis, deposition, and DECOMPOSITION.

global warming is caused primarily by putting too much carbon dioxide into the atmosphere when coal, oil, and natural gas are burned to generate electricity or to run our cars.
