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






2. The act or process of transpiring - or releasing water vapor - especially through the stomata of plant tissue or the pores of the skin.






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






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






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






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






7. A region of the ocean near the equator - characterized by calms - light winds - or squalls.






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






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






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






11. 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.






12. 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.






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






14. When an area of vegetation is cut down and burned before being planted with crops.






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






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






17. A platinum - coated device that oxidizes most of the VOCs and some of the CO that would otherwise be emitted in exhaust - converting them to CO2.






18. Living or derived from living things.






19. Organisms in the first stages of succession.






20. A place where a large quantity of a resource sits for a long period of time.






21. Fires that typically burn only the forest's underbrush and do little damage to mature trees. Surface fires actually serve to protect the forest from more harmful fires by removing underbrush and dead materials that would burn quickly and at high temp






22. When physically treated sewage water is passed into a settling tank - where suspended solids settle out as sludge; chemically treated polymers may be added to help the suspended solids separate and settle out.






23. When each family in a community grows crops for themselves and rely on animal and human labor to plant and harvest crops.






24. The movement of individuals into a population.






25. Is equal to the number of deaths per 1 -000 members of the population in a year.






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






27. The process by which specialized bacteria (mostly anaerobic bacteria) convert ammonia to NOy NO2 - and N2 and release it back to the atmosphere.






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






29. In a sewage treatment plant - the initial filtration that is done to remove debris such as stones - sticks - rags - toys - and other objects that were flushed down the toilet.






30. A symbiotic relationship in which one member is helped by the association and the other is harmed.






31. The management or regulation of a resource so that its use does not exceed the capacity of the resource to regenerate itself.






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






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






34. An underground layer of porous rock - sand - or other material that allows the movement of water between layers of nonporous rock or clay. Aquifers are frequently tapped for wells.






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






36. A layer in a large body of water - such as a lake - that sharply separates regions differing in temperature - so that the temperature gradient across the layer is abrupt.






37. 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.






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






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






40. 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.






41. An opening in the Earth's crust through which molten lava - ash - and gases are ejected.






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






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






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






45. Ozone that exists in the trophosphere.






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






47. The process of soil particles being carried away by wind or water. Erosion moves the smaller particles first and hence degrades the soil to a coarser - sandier - stonier texture.






48. The layer of the Earth between the crust and the core.






49. When grass is consumed by animals at a faster rate than it can regrow.






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