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 removal of all of the trees in an area.






2. 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.






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






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






5. Organisms that reproduce later in life - produce fewer offspring - and devote significant time and energy to the nurturing of their offspring.






6. Calculating risk - or the degree of likelihood that a person will become ill upon exposure to a toxin or pathogen.






7. Involves the removal of the Earth's surface all the way down to the level of the mineral seam.






8. The removal of trees for agricultural purposes or purposes of exportation.






9. Organisms that derive energy from consuming nonliving organic matter.






10. The second-purest form of coal.






11. An effect that results from long -term exposure to low levels of toxin.






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






13. Change in the genetic composition of a population during successive generations as a result of natural selection acting on the genetic variation among individuals and resulting in the development of new species.






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






15. The amount of sugar that the plants produce in photosynthesis and subtracting from it the amount of energy the plants need for growth maintenance - repair - and reproduction.






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






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






18. The process of fusing two nuclei.






19. The result of a pathogen invading a body.






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






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






22. When trees and crops are planted together - creating a mutualistic symbiotic relationship between them.






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






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






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. States that matter can neither be created nor destroyed.






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






29. 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.






30. A semiconductor device that converts the energy of sunlight into electric energy.






31. Organisms that reproduce early in life and often and have a high capacity for reproductive growth.






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. The capacity to do work.






34. The process of burning.






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






36. A severe tropical cyclone originating in the equatorial regions of the Atlantic Ocean or Caribbean Sea or eastern regions of the Pacific Ocean - traveling north - northwest - or northeast from its point of origin - and usually involving heavy rains.






37. When one species feeds on another.






38. An influential theory that concerns the long - term rate of conventional oil (and other fossil fuel) extraction and depletion. It predicts that future world oil production will soon reach a peak and then rapidly decline.






39. The movement of individuals into a population.






40. Radioactive wastes that produce low levels of ionizing radiation.






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






42. The liquid that percolates to the bottom of a landfill.






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






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






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






46. 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.






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






48. The unit used to describe the volume of fossil fuels.






49. Fires that typically burn only the forest's underbrush and do little damage to mature trees. Surface fires actually serve to protect the forest from more harmful fires by removing underbrush and dead materials that would burn quickly and at high temp






50. The solids that remain after the secondary treatment of sewage.
