Different Species of Animals Have Very Different Nutritional Requirements and Gastrointestinal

Different species of animals have very different nutritional requirements and gastrointestinal tract (GIT) specializations, depending on their primary diets. For example, carnivorous animals have relatively short small intestines, fast gut passage rates, and high protein requirements, in accordance with the high-protein, easily digested prey they consume. Based on your knowledge of nutrition and digestion and on the example provided in this scenario, what do you conclude about ruminants, which eat low-protein, difficult-to-digest plant leaves?

A) They have normal nutritional requirements but extremely short GITs and fast gut passage rates to maximize the amount of food passing through the GIT.
B) Their GITs and nutritional requirements are similar to those of carnivores, and they must also eat some animal prey to obtain enough dietary protein.
C) They have reduced protein requirements, long GITs, and slow gut passage rates to extract as many nutrients as possible from their diet.
D) They have reduced protein requirements but GITs and gut passage rates similar to those of carnivores.
