Across
  1. 1. technology that increases manufacturing and efficiency (improved communication creation of CFC)
  2. 4. process of ecological change in an ecosystem over time where one community is replaced
  3. 6. resources that are consumed/used more quickly than created (fossil fuels)
  4. 10. relationship that exists between two organism fighting for the same limited resource
  5. 12. a mature and stable community reached at END of succession
  6. 13. organism that is hunting
  7. 14. any interaction that involves close, physical long term relationship between two species (one always benefits always interspecific)
  8. 21. the actual area in an ecosystem where an organism lives (all abiotic & biotic factors)
  9. 22. normal warming effect when gases trap heat into the atmosphere
  10. 23. reflects a healthy ecosystem
  11. 25. one organism in benefitted the other is neither benefitted of harmed
  12. 30. one organism benefits the other is harmed (cannot kill the host)
  13. 31. technology that provides "clean" energy (decreases fossil fuels, but is expensive & makes nuclear waste)
  14. 32. all the things an organism needs & does w/in its habitat
  15. 33. occurs in area previously occupied, after a disturbance
Down
  1. 2. balance between earth's resources, human needs, and needs of other species
  2. 3. first organism to grow in a new environment, often lunches and mosses (can release soil -> other plants to come in, eventually full ecosystem)
  3. 5. species that hold the ecosystem together
  4. 7. amount of carbon emitted and its environmental impacts
  5. 8. both organism benefit
  6. 9. contributes to pollution and provides clean energy, waste management
  7. 10. no two organisms can occupy the same niche
  8. 11. occurs when a community forms in an area that hasn't previously been occupied
  9. 15. competition between two different species
  10. 16. CFCs deplete ozone layer allowing more UV rays in (burning fossil fuels biggest contributor)
  11. 17. ecosystem that remains constant short periods of change in beginnig
  12. 18. competition between the same species
  13. 19. CFC
  14. 20. organism consumed as food
  15. 24. one animal kills another for food
  16. 26. technology that increases food productivity (irrigation, fertilizers)
  17. 27. CO2, O2, CH4, H2O, trap heat in atmosphere
  18. 28. resources that are produced or replenished more quickly (water)
  19. 29. total amount of variation of life on Earth
