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 cultivation of a single crop on a farm or in a region or country; a single - homogeneous culture without diversity or dissension.






2. 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.






3. A soil horizon - horizon C is made up of larger pieces of rock that have not undergone much weathering.






4. 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.






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






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






7. The process of fusing two nuclei.






8. The result of a pathogen invading a body.






9. Organisms that consume both producers and primary consumers.






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






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






12. 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.






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






14. 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.






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






16. The right - as to fishing or to the use of a riverbed - of one who owns riparian land (the land adjacent to a river or stream).






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






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






19. The process in which animals (and plants!) breathe and give off carbon dioxide from cellular metabolism.






20. 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.






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






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






23. Open or forested areas built at the outer edge of a city.






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






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






26. The movement of individuals into a population.






27. Drilling a hole in the ground that's below the water table to hold waste.






28. Acid rain - acid hail - acid snow; all of which occur as a result of pollution in the atmosphere.






29. Radioactive wastes that produce high levels of ionizing radiation.






30. The low-rainfall region that exists on the leeward (downwind) side of a mountain range. This rain shadow is the result of the mountain range's causing precipitation on the windward side.






31. Biotic and abiotic natural ecosystems.






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






33. The broad category under which selective cutting and shelter-wood cutting fall; selective deforestation.






34. 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.






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






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






37. 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






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






39. The carrier organism through which pathogens can attack.






40. When one species feeds on another.






41. 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.






42. Change in the genetic composition of a population during successive generations as a result of natural selection acting on the genetic variation among individuals and resulting in the development of new species.






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






44. 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.






45. Being extinct or the process of becoming extinct.






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






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






48. The phenomenon whereby the Earth's atmosphere traps solar radiation - caused by the presence in the atmosphere of gases such as carbon dioxide - water vapor - and methane that allow incoming sunlight to pass through - but absorb heat radiated back fr






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






50. 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.
