Across
  1. 2. Broadleaf Forests/ mid-latitude regions, enough moisture to support growth of large, broadleaf deciduous trees
  2. 6. Zone/ the dark regions of the ocean (no light/abyss)
  3. 9. all populations of organisms living close enough for possible interaction
  4. 10. where a freshwater river or stream merges with ocean
  5. 11. Forests/ cone-bearing trees dominate
  6. 12. Ice/ extremely cold; low precipitation; high altitudes
  7. 14. Factors/ living component of the environment
  8. 15. northern coniferous forest (largest terrestrial biome on Earth)
  9. 16. conversion of semi-arid regions to desert
  10. 17. region surrounding the equator between latitudes 23.5 degrees north (Tropic of Cancer) and 23.5 degrees south (Tropic of Capricorn)
  11. 22. small, drifting animals
  12. 24. individuals of the same species living in a particular geographic area
  13. 29. between aquatic and terrestrial ecosystems
  14. 30. Zone/ the seafloor
  15. 31. scientists study how it meets challenges and opportunities of environment
  16. 32. Forests/ warm year-round and lots of precipitation
  17. 33. scientific study of the interactions of organisms with their environment
Down
  1. 1. has low and unpredictable rainfalls
  2. 3. continuously frozen ground found in the tundra
  3. 4. Zone/ part of the ocean where light penetrates
  4. 5. Currents/ river-like flow patterns in oceans
  5. 7. Zone/ the ocean itself (open ocean)
  6. 8. Zone/ where ocean meets land
  7. 10. biotic and abiotic factors in environment
  8. 13. diverse algae and cyanobacteria
  9. 18. animals that drift in the pelagic zone, and most have morphologial features that keep them afloat
  10. 19. all of Earth that is inhabited by life
  11. 20. Shelves/ submerged parts of continents (usually has light and nutrients from the seafloor)
  12. 21. biome that has spiny evergreen shrubs adapted to periodic drought, found where cold ocean currents circulate offshore; mild, rainy winters and long, hot summers
  13. 23. warm, dominated by grasses and scattered trees
  14. 25. high altitudes, north, dwarf woody shrubs, grasses, mosses, and lichens
  15. 26. biotic and abiotic factors present in surroundings
  16. 27. Reefs/ found in the warm tropical waters above the continental shelf
  17. 28. Factors/ nonliving component of the environment
