How can cattle and sheep digest the complex
carbohydrate cellulose while other animals like humans
and pigs cannot digest cellulose?
A. They utilize large volumes of stomach acid to break
down complex carbohydrates.
B. They utilize large volumes of bacteria and enzymes to
break down the complex carbohydrates.
