What is the function of digestion in a rabbit

Copopology is likely a misspelled term. It is possible that you meant to ask about coprophagy, which is the act of animals consuming their own feces for nutritional purposes.

The function of digestion in a rabbit is to break down food into smaller molecules that can be absorbed and utilized by the body for energy, growth, and maintenance. Rabbits have a unique digestive system that includes cecotrophy, where they produce specialized feces called cecotropes that they eat to extract additional nutrients. Additionally, rabbits have a large cecum where fiber is broken down by bacteria and other microbes.
