प्रश्न
What would happen to the number of rabbits and grass plants if the number of foxes decreased?
उत्तर
If the number of foxes decreases, then there will be fewer foxes to consume rabbits as food, so the number of rabbits will increase, which will in turn lead to rabbits consuming more grass plants as food. Hence, grass plants will become sparser.
