Nutritionally, the consumption of feces (coprophagy) makes more sense for hindgut fermenters than foregut fermenters. Why? a. Nutrients produced by microbes in the hindgut are not absorbed; therefore, coprophagy enables hindgut fermenters to absorb nutrients produced by microbes. b. Microbial symbionts are not activated to produce nutrients unless they have passed through the digestive system at least twice. c. Microbial symbionts are rarely excreted; therefore coprophagy enables hindgut fermenters to increase the population of beneficial microbes. d. The microenvironment in the hindgut is more favorable to microbes compared to the foregut.Explanation / Answer
