    Seasonal changes in photoperiod affect the robin's food web
    because robins eat insects, worms, and fruit. Obviously, it is easier for
    robins to find food during a longer photoperiod when the earth is warm so
    that worms are plentiful, fruit is growing, and it is the proper season
    for insects to be available.
