The Immigration of Hawks Into a Different Community

     In a community that has the five trophic levels of plants, crickets, mice, snakes, and hawks, the immigration of even more hawks would definitely cause some big changes!  One likely outcome would be that the hawks would begin feeding off of the mice and snakes.  Both the mice and snake population would therefore decrease, and the plant and cricket population would spike because of the small number of their predators.
   
     Another possibility is that the mice population is filled with disease at the time that the hawks begin feeding on them.  This results in the disease's spreading to the newly introduced hawk population.  The hawk population would then begin to rapidly decrease due to the massive amount of hawk deaths in the community.  The other species of plants and animals would now start to multiply due to the decrease in the numbers of hawks and mice.
