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 movement of individuals out of a population.






2. Biotic and abiotic natural ecosystems.






3. The number of children an average woman will bear during her lifetime; this information is based on an analysis of data from preceding years in the population in question.






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






5. 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.






6. The management of forest plantations for the purpose of harvesting timber.






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






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






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






10. A complex of interrelated food chains in an ecological community.






11. The raising of fish and other aquatic species in captivity for harvest.






12. An animal that only consumes other animals.






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






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






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






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 value of natural resources.






18. The process in which plants absorb ammonium (NH3) - ammonia ions (NH4+) - and nitrate ions (NO3) through their roots.






19. The least pure coal.






20. The molten core of the Earth.






21. 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.






22. 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.






23. The form petroleum takes when in the ground.






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






25. Says that the entropy (disorder) of the universe is increasing. One corollary of the Second Law of thermodynamics is the concept that - in most energy transformations - a significant fraction of energy is lost to the universe as heat.






26. A plate boundary at which plates are moving away from each other. This causes an upwelling of magma from the mantle to cool and form new crust.






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






28. The removal of all of the trees in an area.






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






30. The uppermost horizon of soil. It is primarily made up of organic material - including waste from organisms - the bodies of decomposing organisms - and live organisms.






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






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






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






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






35. Any weathering that's caused by the activities of living organisms.






36. 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.






37. 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.






38. A high-speed - meandering wind current - generally moving from a westerly direction at speeds often exceeding 400 km (250 miles) per hour at altitudes of 15 to 25 km (10 to 15 miles).






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






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






41. Bacteria or fungi that absorb nutrients from nonliving organic matter like plant material - the wastes of living organisms - and corpses. They convert these materials into inorganic forms.






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






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






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






45. The atmospheric pressure conditions corresponding to the periodic warming of El Nino and cooling of La Nina.






46. A process in which an organism is exposed to a toxin at different concentrations - and the dosage that causes the death of the organism is recorded.






47. Devices containing alkaline substances that precipitate out much of the sulfur dioxide from industrial plants.






48. A soil horizon; B receives the minerals and organic materials that are leached out of the A horizon.






49. 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.






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