← Nature & AnimalsWhich nutritional benefit arises within herbivores because of gut microbiomes?
A)Cellulose fermentation degrades plant fiber✓
B)Urea excretion enables water recycling
C)Nitrate reduction creates plant toxins
D)Sulfur reduction causes iron sequestration
💡 Explanation
Cellulose fermentation occurs due to microbes releasing cellulase enzymes that herbivores lack; therefore energy harvest is possible from plant cellulose, rather than animals lacking fiber degradation pathways that have incomplete digestion.
