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. Energy at rest - or stored energy.






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






3. 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






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






5. Formed from populations of different species occupying the same geographic area.






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






7. The process of burning.






8. When water rights are given to those who have historically used the water in a certain area.






9. The practice of alternating the crops grown on a piece of land - for example - corn one year - legumes for two years - and then back to corn.






10. Organisms that consume primary consumers.






11. 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.






12. Close - prolonged associations between two or more different organisms of different species that may - but do not necessarily benefit the members.






13. The fraction of solar energy that is reflected back into space.






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






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






16. 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.






17. Smog resulting from emissions from industry and other sources of gases produced by the burning of fossil fuels.






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






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






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






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






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






23. Any weathering that's caused by the activities of living organisms.






24. 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.






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






26. The process of fusing two nuclei.






27. Also known as transform faults - boundaries at which plates are moving past each other - sideways.






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






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






30. The result of a pathogen invading a body.






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






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






33. 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.






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






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






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






37. When mature trees are cut over a period of time (usually10 -20 years); this leaves mature trees - which can reseed the forest - in place.






38. 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






39. The form petroleum takes when in the ground.






40. 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.






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






42. The process in which soil becomes saltier and saltier until - finally - the salt prevents the growth of plants. Salinization is caused by irrigation because salts brought in with the water remain in the soil as water evaporates.






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






44. Biotic and abiotic natural ecosystems.






45. An estimate of the amount of fossil fuel that can be obtained from reserve.






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






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






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






49. The number of live births per 1 -000 members of the population in a year.






50. A system of vertical and horizontal air circulation predominating in tropical and subtropical regions and creating major weather patterns.
