2. a type of creature that can survive in brine
4. this type of mussel is an invasive species in Alberta
9. this zone is rich in bird life and brings fresh water to the ocean
12. this change in population is most obvious in fresh water systems
13. tiny free floating plant life
15. when thermo-electric plants use water from the environment, the release water that is too ____________ if not treated in a cooling pond
17. an oil spill is an example of this type of population change
18. a flood over flows a stream is an example of this type of population change
19. an adaptation that allows artic fish to survive in cold water
20. warmer water and coral reefs can be found in this zone
24. all of the different species of living organisms living within an ecosystem
26. used to run thermo-electric plants
27. the number of zones in a fresh water body of water
28. air pollution can cause this
29. because of algae bloom, this important part of photosynthesis does not reach the plants below the water
30. in an algae bloom, there is limited amounts of _________

3. the bioluminescent areas on organisms living in the abyssal zone
5. when water has large amounts of carbonates and bicarbonates leaving a white residue
6. this zone in a fresh water body of water has some light penetration and contains many fish species
7. a group of organisms of the same species living in a given area
8. have hard shells and strong attachments to survive in strong water currents
10. the most diverse ecosystem (sodium chloride)
11. the process that cannot occur without light penetrating the water
12. used to measure mountains or sea depths
14. a salt water solution with high concentrations of salt
16. need to be below sea level in order to survive (pressure adaptation)
21. contains some oxygen, but very little
22. a seasonal change where a species may disappear in the winter months
23. responsible for algae bloom
25. starfish and sea urchins would be found in this zone
