Rabbits tend to wander a lot and if it runs into weed or grass... well it eats it. eating weed or grass allows rabbits to gain more energy. if the supplies of grass and or weed increases the population of rabbits would increase too. the more they eat the more energy the have and the more energy the have the more they reproduce. more power = more reproduction more reproduction = increase in population so all in all the more weed, the better it is for rabbits since the amount of food increases
