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 process of burning.






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






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






4. The day-to-day use of environmental resources as food - clothing - and housing.






5. 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.






6. A bloom of dinoflagellates that causes reddish discoloration of coastal ocean waters. Certain dinoflagellates of the genus Gonyamfox produce toxins that kill fish and contaminate shellfish.






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






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






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






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






11. The number of individuals of a population that inhabit a certain unit of land or water area.






12. A semiconductor device that converts the energy of sunlight into electric energy.






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






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






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






16. Any compound that releases hydrogen ions when dissolved in water. Also - a water solution that contains a surplus of hydrogen ions.






17. Calculating risk - or the degree of likelihood that a person will become ill upon exposure to a toxin or pathogen.






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






19. Power generated using water.






20. A long - relatively narrow island running parallel to the mainland-built up by the action of waves and currents and serving to protect the coast from erosion by surf and tidal surges.






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






22. Pollution that does not have a specific point of release - open -loop recycling -when materials are reused to form new products.






23. 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






24. Organisms that consume both producers and primary consumers.






25. Refers to when farmers plant seeds without using a plow to turn the soil.






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






27. The management of forest plantations for the purpose of harvesting timber.






28. When one species feeds on another.






29. Bacteria - virus - or other microorganisms that can cause disease.






30. 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.






31. Graphical representations of populations' ages.






32. The number of children a couple must have in order to replace themselves in a population.






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






34. A plate boundary at which plates are moving away from each other. This causes an upwelling of magma from the mantle to cool and form new crust.






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






36. Living or derived from living things.






37. 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.






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






39. To convert or change into a vapor.






40. An animal that only consumes other animals.






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






42. The biological treatment of wastewater in order to continue to remove biodegradable waste.






43. 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.






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






45. The degree to which a substance is biologically harmful.






46. 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.






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






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






49. The third purest form of coal.






50. The area or environment where an organism or ecological community normally lives or occurs.
