← Nature & AnimalsWhich outcome reduces nutrient absorption in herbivores with limited gut flora diversity?
A)Downregulated cellulase enzyme production✓
B)Decreased absorptive surface area
C)Enhanced intestinal peristaltic contractions
D)Increased microbiome metabolic efficiency
💡 Explanation
Reduced diversity hinders fiber digestion because the *syntrophic metabolism* of gut flora supports cellulase production, therefore inhibiting its production lowers cellulose breakdown rather than changing gut structure or increasing contraction otherwise improving the metabolic efficiency of the smaller microbiome colonies.
