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?

Back

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

Front
