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






2. A symbiotic relationship in which both species benefit.






3. Organisms that consume secondary consumers or other tertiary consumers.






4. Drilling a hole in the ground that's below the water table to hold waste.






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






6. Poor nutrition that results from an insufficient or poorly balanced diet.






7. Power generated using water.






8. Organisms that consume primary consumers.






9. The process that occurs when two different species in a region compete and the better adapted species wins.






10. The form petroleum takes when in the ground.






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






12. The third purest form of coal.






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






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






15. 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.






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






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






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






19. 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






20. The maximum population size that can be supported by the available resources in a region.






21. The development and introduction of new varieties of (mainly) wheat and rice that has increased yields per acre dramatically in countries since the 1960s.






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






23. A process in which rows of crops are plowed across the hillside; this prevents the erosion that can occur when rows are cut up and down on a slope. ...






24. An organism such as a bacterium or protozoan - that obtains its nourishment through the oxidation of inorganic chemical compounds - as opposed to photosynthesis.






25. Creating flat platforms in the hillside that provide a level planting surface - which reduces soil runoff from the slope.






26. 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.






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






28. The part of the wide lower course of a river where its current is met by the tides.






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






30. 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.






31. The cultivation of a single crop on a farm or in a region or country; a single - homogeneous culture without diversity or dissension.






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






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






34. Living or derived from living things.






35. Organisms that consume both producers and primary consumers.






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






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






38. The process in which soil becomes saltier and saltier until - finally - the salt prevents the growth of plants. Salinization is caused by irrigation because salts brought in with the water remain in the soil as water evaporates.






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






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






41. Any weathering that's caused by the activities of living organisms.






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






43. The structure obtained if we organize the amount of energy contained in producers and consumers in an ecosystem by kilocalories per square meter - from largest to smallest.






44. 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.






45. The rocks and Earth that is removed when mining for a commercially valuable mineral resource.






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






47. The result of a pathogen invading a body.






48. The outermost shell of the atmosphere - between the mesosphere and outer space - where temperatures increase steadily with altitude.






49. The part of the Earth and its atmosphere in which living organisms exist or that is capable of supporting life.






50. 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.
