Ecologists in the Galápagos Islands recorded the average beak size in finch populations between 1980 and 2020, according to the chart below. Small- beaked finches are better able to feed on grasses and softer seeds, while large- beaked finches are better able to feed on seeds and nuts. During years with lower precipitation, fewer grasses are available for feeding and the finches consume more seeds. In 1985, 2000, and 2010 were exceptionally dry years, with statistically lower precipitation rates. Which statement below is best supported by the data in the graph? 1980 1990 2000 2010 2020 Year The average beak size in 2000 increased because finches had access to unlimited resources. O The finch population declined from 2015 to 2020 due to a decrease in habitat. Finches with larger beaks were more likely to survive in 2010 because they were able to feed primarily on seeds and nuts during the drought. Finches were better able to find mates, and the population size increaséd in 1985 because of the abundance of grasses. relative beak size
