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 more or less constant winds blowing in horizontal directions over the Earth's surface - as part of Hadley cells.






2. A succession of organisms in an ecological community that constitutes a continuation of food energy from one organism to another as each consumes a lower member and - in turn - is preyed upon by a higher member.






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






4. When one species feeds on another.






5. An introduced - normative species.






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






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






8. The process of burning.






9. The result of graphing a dose-response analysis.






10. Radioactive wastes that produce high levels of ionizing radiation.






11. The movement of individuals out of a population.






12. Ozone that exists in the trophosphere.






13. Nets that are dragged through the water and indiscriminately catch everything in their path.






14. 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).






15. A soil horizon; the layer below the O layer is called the A layer. The A layer is formed of weathered rock - with some organic material; often referred to as topsoil.






16. Refers to resources - such as plants and animals - which can be regenerated if harvested at sustainable yields.






17. Involves the sinking of shafts to reach underground deposits. In this type of mining - networks of tunnels are dug or blasted and humans enter these tunnels in order to manually retrieve the coal.






18. The raising of fish and other aquatic species in captivity for harvest.






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






20. A usually triangular alluvial deposit at the mouth of a river.






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






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






23. Sunlight.






24. Each of the feeding levels in a food chain.






25. 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.






26. This category includes organisms that consume producers (plants and algae).






27. When companies are allowed to buy permits that allow them a certain amount of discharge of substances into certain environmental outlets. If they can reduce their amount of discharge - they are allowed to sell the remaining portion of their permit to






28. In fishing - the use of long lines that have baited hooks and will be taken by numerous aquatic organisms.






29. The form petroleum takes when in the ground.






30. An underground layer of porous rock - sand - or other material that allows the movement of water between layers of nonporous rock or clay. Aquifers are frequently tapped for wells.






31. The process in green plants and certain other organisms by which carbohydrates are synthesized from carbon dioxide and water using light as an energy source. Most forms of photosynthesis release oxygen as a byproduct.






32. The removal of all of the trees in an area.






33. Any waste that poses a danger to human health; it must be dealt with in a different way from other types of waste.






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






35. Pollutants that are formed by the combination of primary pollutants in the atmosphere.






36. Graphical representations of populations' ages.






37. The movement of individuals into a population.






38. The dosage level of a toxin at which a negative effect occurs.






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






40. 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.






41. When physically treated sewage water is passed into a settling tank - where suspended solids settle out as sludge; chemically treated polymers may be added to help the suspended solids separate and settle out.






42. A cyclonic storm having winds ranging from approximately 48 to 121 km (30 to 75 miles) per hour.






43. The point at which 50 percent of the test organisms show a negative effect from a toxin.






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






45. Power generated using water.






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






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






48. An organism that obtains organic food molecules without eating other organisms or substances derived from other organisms. autotrophs use energy from the sun or from the oxidation of inorganic substances to make organic molecules from inorganic ones.






49. Air currents caused by the vertical movement of air due to atmospheric heating and cooling.






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