Across
  1. 4. Aspects of the environment that limit the size a population can reach
  2. 6. The application of scientific discoveries to meet human needs and goals through the development of products and processes
  3. 7. An ecosystem that remains relatively constant over time with predictable changes
  4. 9. A species that holds the ecosystem together and is critical for the survival of other species
  5. 11. An explanation of an observed phenomenon based on research
  6. 12. Standard/”normal” group used for comparison
  7. 13. Impact is independent of population density, therefore the same impact on more dense and less dense populations

  12. 20. An underground layer of permeable rock that can hold water
  13. 21. The actual area in the ecosystem where an organism lives, including all of its abiotic and biotic resources
  14. 23. What is deliberately changed or manipulated in an investigation
  15. 26. Multiple organisms of the same species living together
  16. 27. Individual member of a species or population
  17. 28. A population that grows quickly at first but levels off at the carrying capacity due to limited resources
  18. 30. Recovery of a previously existing ecosystem after a disturbance
  19. 35. All of the things an organisms needs and does within its habitat
  20. 36. The zone of life on Earth, encompassing all of Earth’s ecosystems
  21. 39. The variety of organisms considered at all levels, from populations to ecosystem
  22. 40. Nonliving
  23. 41. A population that grows without limit
  24. 42. Any interaction that involves a close, physical, long-term relationship between two species
  25. 45. A group of organisms of the same species living in the same place
  26. 47. Field of biology that classifies organisms, organizing them based on similar characteristics
  27. 48. Broad concept or principle that describes how something occurs in nature
  28. 49. When a body of water becomes overly enriched with nutrients, causing excessive algae growth
  29. 50. Group(s) being tested
  30. 51. Uses numbers and measurements to quantify something
Down
  1. 1. A mature and stable community of plants and animals that is reached at the end of succession
  2. 2. All of the chemical reactions of each cell in an organism that provide energy for life’s processes and create key molecules
  3. 3. Measure of the number of organisms living in a defined area
  4. 5. Organism hunting/killing another for food
  5. 8. The theoretical maximum population that a given environment could support
  6. 10. What changes in response to the IV; what is measured
  7. 14. The first organisms to grow in a new environment
  8. 16. Balance between Earth’s resources, human needs, and the needs of other species
