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. When one species feeds on another.






2. Organisms that consume both producers and primary consumers.






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






4. 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.






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






6. A climate variation that takes place in the tropical Pacific about every three to seven years - for a duration of about one year.






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






8. 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.






9. An animal that only consumes other animals.






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






11. The second-purest form of coal.






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






13. The capacity to do work.






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






15. The A layer of soil is often referred to as topsoil and is most important for plant growth.






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






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






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






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






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






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






22. A hydrocarbon that forms as sediments are buried and pressurized.






23. An organism that cannot synthesize its own food and is dependent on complex organic substances for nutrition.






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






25. 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.






26. Species that originate and live - or occur naturally - in an area or environment.






27. Organisms that consume primary consumers.






28. Gave the EPA power to set emission standards for major sources of noise - including transportation - machinery - and construction.






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






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






31. 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






32. The amount that the population would grow if there were unlimited resources in its environment.






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






34. The outer part of the Earth - consisting of the crust and upper mantle - approximately 100 km (62 miles) thick.






35. 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.






36. When an area of vegetation is cut down and burned before being planted with crops.






37. 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.






38. 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.






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






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






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






42. An organism that must obtain food energy from secondary sources - for example - by eating plant or animal matter.






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






44. Power generated using water.






45. The removal of select trees in an area; this leaves the majority of the habitat in place and has less of an impact on the ecosystem.






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






47. Countries that have a renewable annual water supply of less than 1 -000 m3 per person.






48. A soil horizon - horizon C is made up of larger pieces of rock that have not undergone much weathering.






49. A group of organisms of the same species that live in the same area.






50. The process of burning.
