Two animal species occur in the same forest-and-grassland region. During spring and summer, both feed on the same plant material. Yet in autumn and winter, one eats nuts in the forest while the other feeds on roots in the grassland. The same predator hunts both species. The numbers of the root-eating animals are decreased the most by this, but they bounce back more quickly because they reproduce at a faster rate. What conclusion can be made about these two animal species?
