← Nature & AnimalsWhich outcome occurs when a grassland grazing animal receives antibiotics?
A)Fiber digestion efficiency is decreased✓
B)Enhanced synthesis of essential vitamins
C)Increased nutrient absorption efficiency occurs
D)Overall microbiome resistance is reduced
💡 Explanation
Antibiotics disrupt the animal's gut microbiome via disruption; the reduction in microbial diversity then hinders the breakdown of complex carbohydrates. Therefore, overall fiber digestion decreases, rather than vitamin synthesis occurring, because the beneficial microbial populations have been reduced or eliminated.
