Across
  1. 3. the total amount of greenhouse gases (including carbon dioxide and methane) that are generated by our actions.
  2. 4. The process in which carbon atoms continually travel from the atmosphere to the earth and then back into the atmosphere
  3. 6. the series of processes by which nitrogen and its compounds are interconverted in the environment and in living organisms, including nitrogen fixation and decomposition.
  4. 7. when water moves from less water to more water
  5. 8. The cycle of processes by whihc water circulates between the earths oceans,atmsphere, and land
  6. 9. the long-term heating of Earth's surface observed since the pre-industrial period
  7. 10. the biogeochemical cycle that describes the transformation and translocation of phosphorus in soil, water, and living and dead organic material.
  8. 13. A chemical process in which oxygen is used to make energy from carbohydrates
  9. 15. light that comes from the sun
  10. 18. net passive movement of molecules from region of higher concentration to region of lower concentration.
  11. 19. a colorless, oderless reactive gas, the chemcial of atonic number 8 and the life suppports componet of the air
  12. 20. rain, snow, sleet, or hail that falls to the ground.
Down
  1. 1. the way in which heat is trapped close to Earth's surface by “greenhouse gases.”
  2. 2. the membrane found in all cells that separates the interior of the cell from the outside environment.
  3. 5. biological mechanisms whereby homeostasis is maintained
  4. 11. The process by which green plants and some other organisms use sunlight to cynthesize foods from carbon dioxide and water
  5. 12. Natural absorbed by plants then goes through a process to then become oxygen
  6. 14. the source of energy for use and storage at the cellular level.
  7. 16. a simple sugar whih is an important energy source in living organisms and is a componet of many carbohydrates
  8. 17. movement of a solute from a region of high electrochemical potential on one side of the cell membrane to a region of lower electrochemical potential on the opposite side.
  9. 21. water molecules diffuse in and out of the cell at the same rate by the process of osmosis.
