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






2. 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.






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






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






5. Says that energy can neither be created nor destroyed; it can only be transferred and transformed.






6. A cooling of the ocean surface off the western coast of South America - occurring periodically every 4 to 12 years and affecting Pacific and other weather patterns.






7. A layer in a large body of water - such as a lake - that sharply separates regions differing in temperature - so that the temperature gradient across the layer is abrupt.






8. The process in green plants and certain other organisms by which carbohydrates are synthesized from carbon dioxide and water using light as an energy source. Most forms of photosynthesis release oxygen as a byproduct.






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






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






11. 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.






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






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






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






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






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






17. A high-speed - meandering wind current - generally moving from a westerly direction at speeds often exceeding 400 km (250 miles) per hour at altitudes of 15 to 25 km (10 to 15 miles).






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






19. 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.






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






21. 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.






22. 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.






23. 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.






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






25. Organisms that consume primary consumers.






26. The energy of motion.






27. A method of supplying irrigation water through tubes that literally drip water onto the soil at the base of each plant.






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






29. 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






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






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






32. A succession of organisms in an ecological community that constitutes a continuation of food energy from one organism to another as each consumes a lower member and - in turn - is preyed upon by a higher member.






33. The molten core of the Earth.






34. The effect caused by a short exposure to a high level of toxin.






35. Using strategies to reduce the amount of risk (the degree of likelihood that a person will become ill upon exposure to a toxin or pathogen).






36. A waste product produced by the burning of coal.






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






38. 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.






39. 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.






40. 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.






41. Radioactive wastes that produce high levels of ionizing radiation.






42. 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.






43. 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.






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






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






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






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






48. 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.






49. Any other species of fish - mammals - or birds that are caught that are not the target organism.






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