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 fishing technique in which the ocean floor is literally scraped by heavy nets that smash everything in their path.






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






3. 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.






4. The least pure coal.






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






6. The process in which animals (and plants!) breathe and give off carbon dioxide from cellular metabolism.






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






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






9. 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.






10. The capacity to do work.






11. A soil horizon; B receives the minerals and organic materials that are leached out of the A horizon.






12. Sunlight.






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






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






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






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






17. The conversion of atmospheric nitrogen into compounds - such as ammonia - by natural agencies or various industrial processes.






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






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






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






21. 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.






22. A stable - mature community in a successive series that has reached equilibrium after having evolved through stages and adapted to its environment.






23. When a species occupies a smaller niche than it would in the absence of competition.






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






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






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






27. An animal that only consumes other animals.






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






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






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






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






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






33. The thinning of the ozone layer over Antarctica (and to some extent - over the Arctic).






34. 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.






35. The value of natural resources.






36. The movement of individuals out of a population.






37. The carrier organism through which pathogens can attack.






38. 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.






39. Soil composed of a mixture of sand - clay - silt - and organic matter.






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






41. The more or less constant winds blowing in horizontal directions over the Earth's surface - as part of Hadley cells.






42. Piles of gangue - which is the waste material that results from mining.






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






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






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






46. Is the practice of planting bands of different crops across a hillside.






47. The phenomenon whereby the Earth's atmosphere traps solar radiation - caused by the presence in the atmosphere of gases such as carbon dioxide - water vapor - and methane that allow incoming sunlight to pass through - but absorb heat radiated back fr






48. 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






49. The rocks and Earth that is removed when mining for a commercially valuable mineral resource.






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