In a community with five trophic levels: plants, crickets, mice, snakes, and hawks, what would happen if more hawks entered the community through immigration? What is my reasoning for the outcome?
Because hawks are predators, that will mean that the population of prey will decrease. Also because snakes are predators too, now there will be an increase in competition between predators. Because of the competition between predators the population of snakes may decrease. With less prey, meaning less food for the hawks, the hawks may emigrate or leave that area to a location with more prey.
The population of crickets on the other hand in my opinion will stay pretty much the same. Of course they will still be preyed upon but I believe that will not affect the population that much. The plant population will most likely remain the same also.
