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. 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).






2. The amount of sugar that the plants produce in photosynthesis and subtracting from it the amount of energy the plants need for growth maintenance - repair - and reproduction.






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






4. The second-purest form of coal.






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






6. 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.






7. Any substance that has an LD50 - of 50 mg or less per kg of body weight.






8. 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.






9. 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.






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






11. The observed effect of the Coriolis force - especially the deflection of an object moving above the Earth - rightward in the Northern Hemisphere - and leftward in the Southern Hemisphere.






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






13. The process of fusing two nuclei.






14. The coarsest soil - with particles 0.05 -2.0 mm in diameter.






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






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






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






18. Air currents caused by the vertical movement of air due to atmospheric heating and cooling.






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






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






21. The region draining into river system or other body of water.






22. The result of a pathogen invading a body.






23. The condition in which - at ecosystem boundaries - there is greater species diversity and biological density than there is in the heart of ecological communities.






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






25. The process of burning.






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






27. Organisms in the first stages of succession.






28. The use of building materials - building placement - and design to passively collect solar energy that can be used to keep a building warm or cool.






29. When companies are allowed to buy permits that allow them a certain amount of discharge of substances into certain environmental outlets. If they can reduce their amount of discharge - they are allowed to sell the remaining portion of their permit to






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






31. The movement of individuals out of a population.






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






33. Refers to resources - such as plants and animals - which can be regenerated if harvested at sustainable yields.






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






35. The least pure coal.






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






37. Transition in species composition of a biological community - often following ecological disturbance of the community; the establishment of a biological community in any area virtually barren of life.






38. When materials - such as plastic or aluminum - are used to rebuild the same product. An example of this is the use of the aluminum from aluminum cans to produce more aluminum cans.






39. The A layer of soil is often referred to as topsoil and is most important for plant growth.






40. Organisms that are capable of interbreeding with one another and incapable of breeding with other species.






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






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






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






44. Ozone that exists in the trophosphere.






45. An erosion-resistant marine ridge or mound consisting chiefly of compacted coral together with algal material and biochemically deposited magnesium and calcium carbonates.






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






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






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






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






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