Across
  1. 3. a group of interbreeding organisms coexisting together
  2. 7. the nonliving physical and chemical conditions affecting organisms
  3. 11. a group of ecosystem classified by climate and plant life
  4. 16. population growth that is unhindered because of the abundance of resources for an ever-increasing population
  5. 17. an organism that eats tertiary consumers
  6. 20. a measure of the total dry mass of organisms (living tissue) within a trophic level in an ecosystem
  7. 22. the process by which certain gases (primarily water vapor, carbon dioxide and methane) trap heat that would otherwise escape the earth and radiate into space
  8. 24. an organism's role in its ecosystem including its habitat, physical requirements, the time of day it is active, its place on the food chain, and when and how it reproduces
  9. 25. rate at which producers in an ecosystem build biomass
  10. 27. a close relationship between two or more species where at least one benefits
  11. 29. the sum of all of Earth's ecosystems classified by climate and plant life
  12. 30. an organism that eats producers
  13. 31. population growth that is controlled by limited resources or the presence of predators or both
Down
  1. 1. evaporation of water from the leaves of plants
  2. 2. one or more populations of individuals that can reproduce under normal conditions, produce fertile offspring, and are reproductively isolated from other such populations
  3. 4. an organism that eats primary consumers
  4. 5. an association of living organisms and their physical environment
  5. 6. organisms that break down the dead remains of other organisms
  6. 8. a series of steps in which organisms transfer energy by eating and being eaten
  7. 9. a symbiotic relationship between two or more organisms of different species where all benefit from the association
  8. 10. a symbiotic relationship between two organisms of different species where one benefits and the other is neither harmed or benefited
  9. 12. any living part of an environment
  10. 13. links all food chains in an ecosystem together
  11. 14. the specific environment of an organism both biotic and abiotic
  12. 15. an organism that eats secondary consumers
  13. 18. a symbiotic relationship between two organism of different species where one benefits and the other is harmed
  14. 19. the study of the interactions between living and nonliving things
  15. 21. organisms that eat living producers and/or other consumers for food
  16. 23. pyramid shaped diagrams that show the amount of energy or matter at each trophic level in an ecosystem
  17. 26. organisms that produce their own food
  18. 28. a group of populations living and interacting in the same area
