Across
  1. 3. off the flow of water, from rain, snow melts, or other sources, over land
  2. 4. a layer of gases surrounding a planet or other material body of sufficient mass[3] that is held in place by the gravity of the body.
  3. 7. reverse of the combined processes of nitration fixation and nitrification; process where nitrogen compounds, through the action of certain bacteria, give up nitrogen gas that becomes part of the atmosphere
  4. 11. uptake the process by which water is absorbed from the soil to other parts of the plant through the roots
  5. 12. process in which the remains of living organisms, after many years, turn into fossil fuel which are burned for energy and give of carbon dioxide
  6. 13. the process where water on the ground surface enters the soil

  6. 9. process carried out by a variety on microorganisms that break down proteins, amino acids and other nitrogen containing compounds in dead and weak organic matter to form ammonia
  7. 10. fixation the chemical processes where atmospheric nitrogen is assimilated into organic compounds
  8. 15. process in which living organisms take in oxygen and release carbon dioxide
  9. 16. the change of the physical state of matter from gas phase into liquid phase
