Infectious diseases — practice question

Two animal species live in the same forest-and-grassland region. During spring and summer, both feed on the same plant material. In autumn and winter, however, one species feeds on nuts in the forest while the other feeds on roots in the grassland. The same predator eats both species. The number of root-eating animals is lowered the most by this predator, but they bounce back more quickly because they breed faster. What conclusion can be drawn about these two animal species?
