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 removal of all of the trees in an area.






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






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






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






5. When populations are well below the size dictated by the carrying capacity of the region they live in - they will grow exponentially - but as they approach the carrying capacity - their growth rate will decrease and the size of the population will ev






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






7. The accumulation of a substance - such as a toxic chemical - in various tissues of a living organism.






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






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






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






11. Being extinct or the process of becoming extinct.






12. An effect that results from long -term exposure to low levels of toxin.






13. 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






14. The second-purest form of coal.






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






16. 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.






17. When the energy released from waste incineration is used to generate electricity.






18. A climate variation that takes place in the tropical Pacific about every three to seven years - for a duration of about one year.






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






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






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






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






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






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






25. The removal of trees for agricultural purposes or purposes of exportation.






26. A usually triangular alluvial deposit at the mouth of a river.






27. Organisms that derive energy from consuming nonliving organic matter.






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






29. A basic substance; chemically - a substance that absorbs hydrogen ions or releases hydroxyl ions; in reference to natural water - a measure of the base content of the water.






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






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






32. Fish farming in which fish are caught in the wild and not raised in captivity for consumption.






33. The least pure coal.






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






35. 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.






36. Ozone that exists in the trophosphere.






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






38. A layer of soil.






39. An organism that cannot synthesize its own food and is dependent on complex organic substances for nutrition.






40. The molten core of the Earth.






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






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






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






44. The third purest form of coal.






45. The form petroleum takes when in the ground.






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






47. 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.






48. The finest soil - made up of particles that are less than 0.002 mm in diameter.






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






50. A lowland area - such as a marsh or swamp - that is saturated with moisture - especially when regarded as the natural habitat of wildlife.
