5. include fixation, ammonification, nitrification, and denitrification
7. makes up more than half of the atmosphere's gas
10. carbon dioxide or other gaseous carbon compounds released into the atmosphere, associated with climate change
11. the biological oxidation of ammonia to nitrate via the intermediary nitrite
14. the first element on the periodic table and the most abundant, making up roughly 90% of atoms in the universe
16. any body of water found on Earth's surface
17. water that exists underground in saturated zones beneath the land surface

1. The change of the solid state of the matter directly on heating to vapor state
