  2. 6. organisms that can eat both plants and animals for food
  3. 9. the step of the water cycle during which water absorbs into the ground and gathers in underground reservoirs
  4. 10. a large underground water reservoir (hint - there is a really big on under the state of FL)
  5. 11. information about the world gathered through the senses
  6. 12. the form in which energy is lost to the environment as it passes from one trophic level to the next
  7. 14. type of microscope that produces a 3D light-based image
  8. 15. information obtained through observation used to support or reject a hypothesis
  9. 18. the type of succession that occurs in an ecosystem that experienced a sudden drop in biodiversity
  10. 20. type of limiting factors made of living things
  11. 21. the type of succession that occurs in a previously uninhabited area with no established nutrients
  12. 24. the largest carbon reservoir
  13. 27. the step of the water cycle that occurs when water evaporates from the tissues of plants
  14. 30. the percentage of energy that is passed from one trophic level to the next
  15. 31. a system of interdependent species based on energy transfer between trophic levels
  16. 32. the property of water that allows it to dissolve many substances easily
  17. 33. an organism that feeds on dead organic matter, recycling its trapped nutrients back into the environment
  18. 34. the step of the carbon cycle caused by burning fossil fuels

  11. 19. type of limiting factor made of nonliving things/resources
  12. 22. an explanation of phenomena in the world based on observations
  13. 23. the biogeochemical cycle that includes evaporation, precipitation, and runoff

  17. 29. the addition of new individuals to a population from another population
  18. 35. an abiotic limiting factor of aquatic ecosystems that measures the amount of salt dissolved in the water
