Which description best contrasts herbivores and carnivores? Herbivores have specialized teeth and digestive systems, whereas carnivores require no diet specialization. Herbivores are able to digest food with relative ease, whereas carnivores have to soften food with bacteria. Herbivores work harder to find and eat food, whereas carnivores are most often scavengers that expel little energy. Herbivores eat frequently in order to sustain nutrients, whereas carnivores eat more nutritious meals less often.
