I want to know the answer to the following question:
What process of breaking down cellulose do herbivores rely on for their essential nutrients?
All the background I'm provided with is that "" Many herbivores rely on bacterial fermentation to create digestible nutrients from indigestible plant cellulose, while obligate carnivores must eat animal meats to obtain certain vitamins or nutrients their bodies cannot otherwise synthesize.". Is that enough to answer the question?
