The primary consumers like rabbits or other small animals that are normally eaten by the secondary consumers (snakes) would over populate and eat all of the producers (plants) and the plants would die out. This would eventually lead to the decrease of the primary consumer (rabbit/small animals) population.
Vitamins is the correct answer since they would provide just nutrients not ATP themselves
