The rumen is an ________ habitat that depends on ________ to digest cellulose for ruminant animals.
A) aerobic / cellulolytic fungi
B) aerobic / cellulolytic and fermentative bacteria
C) anaerobic / methanogens
D) anaerobic / cellulolytic and fermentative bacteria

Question

Quizplus · Accepted Answer

The rumen is an anaerobic habitat, meaning it lacks oxygen. Ruminant animals rely on cellulolytic and fermentative bacteria to digest cellulose in their feed. Methanogens also play a role in the rumen ecosystem but they do not directly digest cellulose. Option A is incorrect because aerobic bacteria require oxygen to survive. Option B is partially correct as it includes cellulolytic bacteria but not fermentative bacteria. Option C is incorrect as methanogens are not responsible for cellulose digestion.
