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






2. A symbiotic relationship in which one member is helped by the association and the other is harmed.






3. The part of the mantle that lies just below the lithosphere.






4. The result of vibrations (often due to plate movements) deep in the Earth that release energy. They often occur as two plates slide past one another at a transform boundary.






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






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






7. 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.






8. 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.






9. When water rights are given to those who have historically used the water in a certain area.






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






11. The right - as to fishing or to the use of a riverbed - of one who owns riparian land (the land adjacent to a river or stream).






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






13. A model that's used to predict population trends based on the birth and death rates as well as economic status of a population.






14. The capacity to do work.






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






16. 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






17. The use of building materials - building placement - and design to passively collect solar energy that can be used to keep a building warm or cool.






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






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






20. The process of burning.






21. Says that the entropy (disorder) of the universe is increasing. One corollary of the Second Law of thermodynamics is the concept that - in most energy transformations - a significant fraction of energy is lost to the universe as heat.






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






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






24. 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.






25. A complex of interrelated food chains in an ecological community.






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






27. Soil with particles 0.002 -0.05 mm in diameter.






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






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






30. Organisms that consume primary consumers.






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. 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.






33. A plate boundary where two plates are moving toward each other.






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






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






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






37. The process of soil particles being carried away by wind or water. Erosion moves the smaller particles first and hence degrades the soil to a coarser - sandier - stonier texture.






38. Living or derived from living things.






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






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






41. A tank filled with aerobic bacteria that's used to treat sewage.






42. Pertaining to factors or things that are separate and independent from living things; nonliving.






43. 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.






44. The energy of motion.






45. The number of individuals of a population that inhabit a certain unit of land or water area.






46. An introduced - normative species.






47. The dark - crumbly - nutrient-rich material that results from the decomposition of organic material.






48. 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.






49. The form petroleum takes when in the ground.






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