APES semester 1 exam review
questions and answers11
replacement level fertility - ANSWERS-total fertility rate needed for a population to remain
constant
biomagnification - ANSWERS-accumulation of pollutants at successive levels of the food chain
bioaccumulation - ANSWERS-the build up of a substance (usually a toxin) as it passes through a
food chain
demographic transition - ANSWERS-change in a population from high birth and death rates to
low birth and death rates
intercropping - ANSWERS-Growing two or more different crops at the same time on a plot.
clean water act - ANSWERS-set maximum permissible amounts of water pollutants that can be
discharged into waterways..aim to make surface waters swimmable and fishable
biological controls - ANSWERS-use of natural predators, pathogens, or competitors to regulate
pest populations
IPM - ANSWERS-integrated pest management. the use of several different methods of control to
reduce the p[population of a particular pest, minimizing the use of pesticides

reformed by geological processes
ecology - ANSWERS-the study of living things
