One of the most common such species is the eastern meadowlark. The graph shows the number of eastern meadowlarks in the United States between 1980 and 2005, according to a national environmental society's bird count. Assume that the population continues to decrease exponentially. 50 44 Meadowlark (16, 30) population 30 (x 1000) 10 5 10 15 20 25 Years since 1980 (a) What was the meadowlark population in 1980? meadowlarks (b) Find the one-year decay factor a.
