    Carnivorous mammals will be adversely affected by the introduction of carnivorous bird.

    Explanation:

    Carnivorous mammals will be affected because these carnivorous mammals feed on the large fishes and due to high feeding of carnivorous bird, these large fish decrease in population so food is not sufficient for the carnivorous mammals and they will die because of hunger and whole ecosystem will be disturbed.
