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






2. The development and introduction of new varieties of (mainly) wheat and rice that has increased yields per acre dramatically in countries since the 1960s.






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






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






5. A model that's used to predict population trends based on the birth and death rates as well as economic status of a population.






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






7. An animal that only consumes other animals.






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






9. Land that's fit to be cultivated.






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






11. A layer of soil.






12. 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.






13. Biotic and abiotic natural ecosystems.






14. 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.






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






16. The second-purest form of coal.






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






18. The process by which - according to Darwin's theory of evolution - only the organisms best adapted to their environment tend to survive and transmit their genetic characteristics in increasing numbers to succeeding generations - while those less adap






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






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






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






22. Organisms that reproduce later in life - produce fewer offspring - and devote significant time and energy to the nurturing of their offspring.






23. The random fluctuations in the frequency of the appearance of a gene in a small isolated population - presumably owing to chance - rather than natural selection.






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






25. Power generated using water.






26. Acid rain - acid hail - acid snow; all of which occur as a result of pollution in the atmosphere.






27. Any substance than is inhaled - ingested - or absorbed at dosages sufficient to damage a living organism.






28. An organism that is capable of converting radiant energy or chemical energy into carbohydrates.






29. The process in which soil bacteria convert ammonium (NH4+) to a form that can be used by plants; nitrate - or NO3.






30. 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.






31. The result of graphing a dose-response analysis.






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






33. In fishing - the use of long lines that have baited hooks and will be taken by numerous aquatic organisms.






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






35. When the size of an organism's natural habitat is reduced - or when development occurs that isolates a habitat.






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






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






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






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






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






41. Areas where cutting has occurred and a new - younger forest has arisen.






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






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






44. The maintenance of a species or ecosystem in order to ensure their perpetuation - with no concern as to their potential monetary value






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






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






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






48. In tectonic plates - the site at which an oceanic plate is sliding under a continental plate.






49. The amount of the Earth's surface that's necessary to supply the needs of - and dispose of the waste from a particular population.






50. 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
