LS.5.2: 2024 EOG Item Set

Amy and Belle were discussing ways to help the fox population. There is a grassland ecosystem nearby with these characteristics:

-There are few trees, shrubs, and ferns, and no berry bushes in the grassland;
-the river does not flow through the grassland;
-some rabbits are found in the grassland, but because there are few hiding places, the rabbits are easily caught by hawks.

Amy states that the remaining foxes should be removed from the forest and taken to the grassland. Belle disagrees. Which student is correct?

• Amy, because there will be more food for the foxes in the grassland ecosystem

• Amy, because there is no water, and therefore no toxin present in the grassland ecosystem

• Belle, because there will be fewer predators for the foxes in the grassland ecosystem

• Belle, because the foxes will not have the resources they need to survive in the grassland ecosystem

Scientists have found a way to remove the toxin from the river. What effect would this have on the berry bush population?

• The berry bush population would increase because there would be more foxes.

• The berry bush population would decrease because there would be more foxes.

• The berry bush population would increase because there would be fewer foxes.

• The berry bush population would decrease because there would be fewer foxes.
