<em>The carrying capacity of the ecosystem for the white-footed mouse reduced in response to the changes in the amount of worm infected mice in the population.</em>
The carrying capacity of an ecosystem for a particular population of organisms is the maximum number of organisms the ecosystem can support based on the resources it has.
<u>The ideal carrying capacity of the ecosystem for the white-footed mouse oscillates between 36 to 40 in graph 1. The carrying capacity range reduced in graph 2 from 36 - 40 to 30 - 36 as a result of changes made to the number of mice infected with parasitic worms in the population of the animal. </u>
Thus, the introduction of more worm-infected mice into the population probably put more pressure on the ecosystem resources thereby reducing the carrying capacity.
Have you ever done a Punnett Square? This question forces you to make one. If your cross a homozygous type A (AA) and homozygous type O (OO) you should get 100% AO. Understanding genetics, an AO gene means a type A blood. Therefore, it's 100% type A blood (AO).
