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






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






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






4. The total sum of a species' use of the biotic and abiotic resources in its environment.






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






6. Can consist of hazardous waste - industrial solid waste - or municipal waste. Many types of solid waste provide a threat to human health and the environment.






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






8. 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






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






10. A cooling of the ocean surface off the western coast of South America - occurring periodically every 4 to 12 years and affecting Pacific and other weather patterns.






11. Organisms in the first stages of succession.






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






13. The carrier organism through which pathogens can attack.






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






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






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






17. When a species occupies a smaller niche than it would in the absence of competition.






18. The result of vibrations (often due to plate movements) deep in the Earth that release energy. They often occur as two plates slide past one another at a transform boundary.






19. The process of burning.






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






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






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






23. 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.






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






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






26. 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.






27. 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.






28. 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.






29. When one species feeds on another.






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






31. Biotic and abiotic natural ecosystems.






32. 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.






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






34. A program funded by the federal government and a trust that's funded by taxes on chemicals; identifies pollutants and cleans up hazardous waste sites.






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






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






37. Species that originate and live - or occur naturally - in an area or environment.






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






39. A cyclonic storm having winds ranging from approximately 48 to 121 km (30 to 75 miles) per hour.






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






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






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






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






44. A model that's used to predict population trends based on the birth and death rates as well as economic status of a population.






45. Resources that are often formed by very slow geologic processes - so we consider them incapable of being regenerated within the realm of human existence.






46. To convert or change into a vapor.






47. The removal of select trees in an area; this leaves the majority of the habitat in place and has less of an impact on the ecosystem.






48. Ozone that exists in the trophosphere.






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






50. A process in which cold - often nutrient-rich - waters from the ocean depths rise to the surface.
