What would happen to the number of grass plants and foxes if the number of rabbits increased?

उत्तर

If the number of rabbits increases, it will lead to rabbits consuming more grass plants, and hence grass plants will become sparser. As foxes consume rabbits, any increase in the number of rabbits will lead to an increase in the number of foxes.
