Across
  1. 1. a colorless, odorless gas produced by burning carbon and organic compounds and by respiration
  2. 5. nitrogen moves through both living and non-living things: the atmosphere, soil, water, plants, animals and bacteria.
  3. 6. a microscopic membrane of lipids and proteins which forms the external boundary of the cytoplasm of a cell or encloses a vacuole
  4. 10. the process of producing cellular energy involving oxygen
  5. 11. the movement of ions or molecules across a cell membrane into a region of higher concentration, assisted by enzymes and requiring energy.
  6. 12. the biogeochemical cycle that describes the movement of phosphorus through the lithosphere, hydrosphere, and biosphere.
  7. 14. component of the air
  8. 16. having a lower osmotic pressure than a particular fluid
  9. 17. the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water
  10. 18. taking place with normal contraction
Down
  1. 1. the process by which organisms combine oxygen with foodstuff molecules, diverting the chemical energy in these substances into life-sustaining activities and discarding, as waste products, carbon dioxide and water
  2. 2. a process by which molecules of a solvent tend to pass through a semipermeable membrane from a less concentrated solution into a more concentrated one, thus equalizing the concentrations on each side of the membrane
  3. 3. respiration using electron acceptors other than molecular oxygen
  4. 4. the cycle of processes by which water circulates between the earth's oceans, atmosphere, and land, involving precipitation as rain and snow, drainage in streams and rivers, and return to the atmosphere by evaporation and transpiration.
  5. 7. a change in global or regional climate patterns
  6. 8. the series of processes by which carbon compounds are interconverted in the environment,
  7. 9. the intermingling of substances by the natural movement of their particles.
  8. 13. having a higher osmotic pressure than a particular fluid
  9. 15. simple sugar
  10. 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
