18. This category includes organisms that consume producers (plants and algae).






19. A nuclear reaction in which an atomic nucleus - especially a heavy nucleus such as an isotope of uranium - splits into fragments - usually two fragments of comparable mass - releasing from 100 million to several hundred million electron volts of ener






20. To convert or change into a vapor.

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






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






28. 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.






29. A hydrocarbon deposit - such as petroleum - coal - or natural gas - derived from living matter of a previous geologic time and used for fuel.






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






31. The process of burning.

37. The cleanest-burning coal; almost pure carbon.






38. 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.






39. The coarsest soil - with particles 0.05 -2.0 mm in diameter.






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






41. 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.






42. Graphical representations of populations' ages.






43. A process in which rows of crops are plowed across the hillside; this prevents the erosion that can occur when rows are cut up and down on a slope. ...






44. Organisms that reproduce early in life and often and have a high capacity for reproductive growth.






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






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

49. Any water that has been used by humans. This includes human sewage - water drained from showers - tubs - sinks - dishwashers - washing machines - water from industrial processes - and storm water runoff.
