A blueberry farmer is concerned that animals are eating his berries before harvest.  He wants to determine whether birds or rodents may be eating the berries.  Because he has observed birds in his fields every morning, he hypothesizes that birds are eating the berries and having a negative impact on his harvest.  He predicts that if he excludes birds from blueberry bushes, he will harvest more berries.  In an experimental blueberry field, he covers half the rows with nets that keep birds out; the other rows remain as they were.  He weighs the number of berries harvested from each row over an eight week period. What is the dependent variable in the farmer’s experiment?
