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






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






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






46. The process by which - according to Darwin's theory of evolution - only the organisms best adapted to their environment tend to survive and transmit their genetic characteristics in increasing numbers to succeeding generations - while those less adap
