What statement most directly demonstrates a way that the geosphere is involved in the nitrogen cycle
Ulleksa [173]

B. bacteria that convert ammonia into nitrites and nitrates are found in the soil  

This statement best demonstrates a way that the geo-sphere is involved in the nitrogen cycle.

A nitrogen cycle is defined as the movement of nitrogen between the atmosphere, biosphere, and geo-sphere in different forms. Ammonia is converted to nitrates by nitrifying bacteria in the soil. Then the plants absorb these nitrates from the soil and use these to build up proteins.
