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 point at which 50 percent of the test organisms die from a toxin.






2. The process of burning.






3. The process in which plants absorb ammonium (NH3) - ammonia ions (NH4+) - and nitrate ions (NO3) through their roots.






4. Organisms that are capable of interbreeding with one another and incapable of breeding with other species.






5. A process in which cold - often nutrient-rich - waters from the ocean depths rise to the surface.






6. Is equal to the number of deaths per 1 -000 members of the population in a year.






7. The use of devices - such as solar panels - to collect - focus - transport - or store solar energy.






8. Areas where cutting has occurred and a new - younger forest has arisen.






9. The process by which specialized bacteria (mostly anaerobic bacteria) convert ammonia to NOy NO2 - and N2 and release it back to the atmosphere.






10. Soil composed of a mixture of sand - clay - silt - and organic matter.






11. The area or environment where an organism or ecological community normally lives or occurs.






12. Any compound that releases hydrogen ions when dissolved in water. Also - a water solution that contains a surplus of hydrogen ions.






13. The gaseous mass or envelope surrounding a celestial body - especially the one surrounding the Earth - which is retained by the celestial body's gravitational field.






14. A place where a large quantity of a resource sits for a long period of time.






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






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






17. Bacteria or fungi that absorb nutrients from nonliving organic matter like plant material - the wastes of living organisms - and corpses. They convert these materials into inorganic forms.






18. Organisms in the first stages of succession.






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






20. The act or process of transpiring - or releasing water vapor - especially through the stomata of plant tissue or the pores of the skin.






21. A basic substance; chemically - a substance that absorbs hydrogen ions or releases hydroxyl ions; in reference to natural water - a measure of the base content of the water.






22. Refers to when farmers plant seeds without using a plow to turn the soil.






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






24. Graphical representations of populations' ages.






25. The broad category under which selective cutting and shelter-wood cutting fall; selective deforestation.






26. Land that's fit to be cultivated.






27. The movement of individuals into a population.






28. 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.






29. 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.






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






31. The gradual breakdown of rock into smaller and smaller particles - caused by natural chemical - physical - and biological factors.






32. The movement of individuals out of a population.






33. The vertical movement of a mass of matter due to heating and cooling; this can happen in both the atmosphere and Earth's mantle.






34. When soil becomes water-logged and then dries out - and salt forms a layer on its surface.






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






36. The water from which a river rises; a source.






37. The biological treatment of wastewater in order to continue to remove biodegradable waste.






38. When photochemical smog - NOx compounds - VOCs - and ozone combine to form smog with a brownish hue.






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






40. The number of children an average woman will bear during her lifetime; this information is based on an analysis of data from preceding years in the population in question.






41. A hydrocarbon deposit - such as petroleum - coal - or natural gas - derived from living matter of a previous geologic time and used for fuel.






42. Smog resulting from emissions from industry and other sources of gases produced by the burning of fossil fuels.






43. An organism that is capable of converting radiant energy or chemical energy into carbohydrates.






44. Non-moving sources of pollution - such as factories.






45. When ecological succession begins in a virtually lifeless area - such as the area behind a moving glacier.






46. The carrier organism through which pathogens can attack.






47. Devices containing alkaline substances that precipitate out much of the sulfur dioxide from industrial plants.






48. Using strategies to reduce the amount of risk (the degree of likelihood that a person will become ill upon exposure to a toxin or pathogen).






49. Pollution that does not have a specific point of release - open -loop recycling -when materials are reused to form new products.






50. The bedrock - which lies below all of the other layers of soil - is referred to as the R horizon.
