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






2. An intensification of the Greenhouse Effect due to the increased presence of heat-trapping gases in the atmosphere.






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






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






5. Living or derived from living things.






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






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






8. 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.






9. Organisms that consume primary consumers.






10. The amount of time it takes for half of a radioactive sample to disappear.






11. The gaseous mass or envelope surrounding a celestial body - especially the one surrounding the Earth - which is retained by the celestial body's gravitational field.






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






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






14. The result of chemical interaction with the bedrock that is typical of the action of both water and atmospheric gases.






15. A nuclear reaction in which an atomic nucleus - especially a heavy nucleus such as an isotope of uranium - splits into fragments - usually two fragments of comparable mass - releasing from 100 million to several hundred million electron volts of ener






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






17. One that has never been cut; these forests have not been seriously disturbed for several hundred years.






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






19. The place where two plates abut each other.






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






21. The least pure coal.






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






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






24. A hydrocarbon deposit - such as petroleum - coal - or natural gas - derived from living matter of a previous geologic time and used for fuel.






25. The value of natural resources.






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






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






28. In a sewage treatment plant - the initial filtration that is done to remove debris such as stones - sticks - rags - toys - and other objects that were flushed down the toilet.






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






30. Organisms that consume both producers and primary consumers.






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






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






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






34. The region draining into river system or other body of water.






35. A specific location from which pollution is released; an example of a point source location is a factory where wood is being burned.






36. When the energy released from waste incineration is used to generate electricity.






37. Biotic and abiotic natural ecosystems.






38. When one species feeds on another.






39. The process by which the concentration of toxic substances increases in each successive link in the food chain.






40. 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.






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






42. The second-purest form of coal.






43. 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.






44. Pollutants that are released directly into the lower atmosphere.






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






46. A region of the ocean near the equator - characterized by calms - light winds - or squalls.






47. A species whose very presence contributes to an ecosystem's diversity and whose extinction would consequently lead to the extinction of other forms of life.






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






49. Smog resulting from emissions from industry and other sources of gases produced by the burning of fossil fuels - especially coal.






50. Occurs when infection causes a change in the state of health.
