Nitrogen fixation is the process by which nitrogen is taken from its relatively inert molecular form (N2) in the atmosphere and converted into nitrogen compounds useful for other chemical processes (such as, notably, ammonia, nitrate and nitrogen dioxide).
Nitrogen fixation is performed naturally by certain types of anaerobic bacteria. Legumes such as clover contain symbiotic bacteria of this type within nodules in their root systems, producing nitrogen compounds that help to fertilize the soil. See George Washington Carver.
Nitrogen can also be artificially fixed for use as fertilizer or in other industrial processes. The most popular method is by the Haber process. Artificial fertilizer production has achieved such scale that it is now the largest source of fixed nitrogen in the Earth's ecosystem.

Answer:
Cellular respiration results in net output of energy.
Explanation:
Cellular respiration can be described as a process in which cells convert glucose and oxygen into carbon dioxide and water. Energy is released in the form of ATP in the process hence, it gives a net output of energy.
As a result of cellular respiration, two molecules of energy (ATP) are produced in glycolysis, Kreb's cycle also produces 2 molecules of ATP, 34 molecules of energy (ATP) are produced by the electron transport chain
I believe its a because the sun is located in a spiral arm of the galaxy so we would be farther away from the center than we would be if we were not in an arm hope it helps
