4. 3 All of the following are nektonic EXCEPT: A Dolphin B Perch C Sting ray D Sea Urchin

5. 4 Which of the following is FALSE when considering carbon A Carbon can be found in the atmosphere & in the water in the form of carbon dioxide B Carbon is found in organisms as organic molecules such as glucose & fat C An increase in producers will increase the amount of atmospheric carbon D Carbon can be burried in the ground as fossil fuel

6. 5 Swamps, bogs, lakes, and ponds are considered: A Lentic B Lotic C Wetlands D Estuaries

7. 6 Which of the following is FALSE when considering global freshwater: A It covers around 1% of the planet’s surface B It contains more biodiverse species than can be found in saltwater C The concentration of dissolved salts within freshwater is less than 1% D Glaciers, rivers, wells, and aquifers are all examples of freshwater

8. 7 Which of the following represents the carrying capacity of an environment: B C D A

9. 8 Which of the following is FALSE when considering salt water A Salt water covers the majority of the planet’s surface B Saltwater is more biodiverse than land C Saltwater is connected to regulation of the planet’s temperature D Saltwater is responsible for storing a large amount of the planet’s carbon dioxide

10. 9 While participating in a geological survey, you measure from the high-tide mark to the edge of the continental shelf in an area off of the Florida Keys. You measured: A The continental shelf B The intertidal zone C The benthic zone, where the majority of species exist in the oceans D The coastal zone

11. 10 Which of the following is UNTRUE about a predator/prey relationship: A as prey increases, predators will increase B as predators increase, prey decreases C as predators increase, prey increases D as prey decreases, predators will decrease

12. 11 You are in a submersible found below 100 meters within the twilight zone. Which of the following colors would you only be able to see if you shined a spotlight/flashlight on something of that color: A Blue B Ultra-violet C Red D Green

13. 12 You would be able to find a large quantity of phytoplankton in a(n) A Eutrophic Lake B Oligotrophic Lake C 2nd Order Stream D Headwaters

14. 13 Which of the following would be true when considering a population without any limiting factors: A Birth Rate = Death Rate B The population growth chart would exponentially increase C The population growth chart would increase with a steady slope D Birth Rate < Death Rate

15. 14 When considering the carbon cycle, which of the following is causing a rapid increase in atmospheric carbon dioxide: A The hunting of large animals B The burning of fossil fuel C The planting of trees D The decomposition of humans in graves

16. 15 Which chemical is predominantly responsible for acid rain: A sulfur dioxide B carbon dioxide C chlorine dioxide D methane gas

17. 16 Lakes undergo turn over throughout the changing seasons because: A The gravitational pull from the moon is greater in the winter within the Northern Hemisphere B The thermocline gets rapidly colder in shallow lakes C The hypolimnion is at a higher density than the epilimnion D The lakes are not affected by tides or currents so the daily temperature associated with depth stays constant
