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. Organisms that consume primary consumers.






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






3. Organisms that consume both producers and primary consumers.






4. The form petroleum takes when in the ground.






5. Open or forested areas built at the outer edge of a city.






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






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






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






9. An area in which a particular mineral is concentrated - mining -the excavation of the Earth for the purpose of extracting ore or minerals.






10. 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.






11. 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.






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






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






14. Being extinct or the process of becoming extinct.






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






16. A process that allows the organic material in solid waste to be decomposed and reintroduced into the soil - often as fertilizer.






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






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






19. A basic substance; chemically - a substance that absorbs hydrogen ions or releases hydroxyl ions; in reference to natural water - a measure of the base content of the water.






20. Urban areas that heat up more quickly and retain heat more than do nonurban areas.






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






22. The point at which 50 percent of the test organisms die from a toxin.






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






24. 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.






25. 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.






26. A usually triangular alluvial deposit at the mouth of a river.






27. The result of a pathogen invading a body.






28. Bacteria or fungi that absorb nutrients from nonliving organic matter like plant material - the wastes of living organisms - and corpses. They convert these materials into inorganic forms.






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






30. Also known as plantations - these are planted and managed tracts of trees of the same age that are harvested for commercial use.






31. Graphical representations of populations' ages.






32. The day-to-day variations in temperature - air pressure - wind - humidity - and precipitation mediated by the atmosphere in a given region.






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






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






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






36. Can consist of hazardous waste - industrial solid waste - or municipal waste. Many types of solid waste provide a threat to human health and the environment.






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






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






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






40. A process in which an organism is exposed to a toxin at different concentrations - and the dosage that causes the death of the organism is recorded.






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






42. 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.






43. 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.






44. 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.






45. 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.






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






47. The use of devices - such as solar panels - to collect - focus - transport - or store solar energy.






48. The amount of energy that plants pass on to the community of herbivores in an ecosystem.






49. Any noise that causes stress or has the potential to damage human health.






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