Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. The effect caused by a short exposure to a high level of toxin.






2. The industry or occupation devoted to the catching - processing - or selling of fish - shellfish - or other aquatic animals.






3. A layer in a large body of water - such as a lake - that sharply separates regions differing in temperature - so that the temperature gradient across the layer is abrupt.






4. Any other species of fish - mammals - or birds that are caught that are not the target organism.






5. When the size of an organism's natural habitat is reduced - or when development occurs that isolates a habitat.






6. The day-to-day variations in temperature - air pressure - wind - humidity - and precipitation mediated by the atmosphere in a given region.






7. Any process that breaks rock down into smaller pieces without changing the chemistry of the rock; typically wind and water.






8. The process by which - according to Darwin's theory of evolution - only the organisms best adapted to their environment tend to survive and transmit their genetic characteristics in increasing numbers to succeeding generations - while those less adap






9. The degree to which a substance is biologically harmful.






10. Organisms that consume primary consumers.






11. The number of children a couple must have in order to replace themselves in a population.






12. Close - prolonged associations between two or more different organisms of different species that may - but do not necessarily benefit the members.






13. The atmospheric pressure conditions corresponding to the periodic warming of El Nino and cooling of La Nina.






14. When grass is consumed by animals at a faster rate than it can regrow.






15. The management of forest plantations for the purpose of harvesting timber.






16. A process that allows the organic material in solid waste to be decomposed and reintroduced into the soil - often as fertilizer.






17. A group of organisms of the same species that live in the same area.






18. Urban areas that heat up more quickly and retain heat more than do nonurban areas.






19. Bacteria - virus - or other microorganisms that can cause disease.






20. A nuclear reaction in which an atomic nucleus - especially a heavy nucleus such as an isotope of uranium - splits into fragments - usually two fragments of comparable mass - releasing from 100 million to several hundred million electron volts of ener






21. Graphical representations of populations' ages.






22. The maintenance of a species or ecosystem in order to ensure their perpetuation - with no concern as to their potential monetary value






23. The cleanest-burning coal; almost pure carbon.






24. When the energy released from waste incineration is used to generate electricity.






25. A bloom of dinoflagellates that causes reddish discoloration of coastal ocean waters. Certain dinoflagellates of the genus Gonyamfox produce toxins that kill fish and contaminate shellfish.






26. The accumulation of a substance - such as a toxic chemical - in various tissues of a living organism.






27. Sunlight.






28. Pollutants that are released directly into the lower atmosphere.






29. The movement of individuals into a population.






30. A long - relatively narrow island running parallel to the mainland-built up by the action of waves and currents and serving to protect the coast from erosion by surf and tidal surges.






31. When the signs and symptoms of an illness can be attributed to a specific infectious organism that resides in the building.






32. A fiscal policy that lowers taxes on income - including wages and profit - and raises taxes on consumption - particularly the unsustainable consumption of non-renewable resources.






33. Resources that are often formed by very slow geologic processes - so we consider them incapable of being regenerated within the realm of human existence.






34. Any water that has been used by humans. This includes human sewage - water drained from showers - tubs - sinks - dishwashers - washing machines - water from industrial processes - and storm water runoff.






35. The process in which animals (and plants!) breathe and give off carbon dioxide from cellular metabolism.






36. The management or regulation of a resource so that its use does not exceed the capacity of the resource to regenerate itself.






37. Any noise that causes stress or has the potential to damage human health.






38. Countries that have a renewable annual water supply of about 1 -000 -2 -000 m3 per person.






39. A lowland area - such as a marsh or swamp - that is saturated with moisture - especially when regarded as the natural habitat of wildlife.






40. Power generated using water.






41. States that matter can neither be created nor destroyed.






42. The process in which soil bacteria convert ammonium (NH4+) to a form that can be used by plants; nitrate - or NO3.






43. Fish farming in which fish are caught in the wild and not raised in captivity for consumption.






44. Says that energy can neither be created nor destroyed; it can only be transferred and transformed.






45. Living or derived from living things.






46. The low-rainfall region that exists on the leeward (downwind) side of a mountain range. This rain shadow is the result of the mountain range's causing precipitation on the windward side.






47. The carrier organism through which pathogens can attack.






48. When populations are well below the size dictated by the carrying capacity of the region they live in - they will grow exponentially - but as they approach the carrying capacity - their growth rate will decrease and the size of the population will ev






49. Any substance that has an LD50 - of 50 mg or less per kg of body weight.






50. A system of vertical and horizontal air circulation predominating in tropical and subtropical regions and creating major weather patterns.
