Pandas primarily feed on bamboo, which makes up about 99% of their diet. Despite being part of the order Carnivora, giant pandas have evolved to mainly consume this fibrous plant. They require large quantities of bamboo daily, often eating between 20 to 40 pounds, due to its low nutritional value. Pandas will also consume other plant materials and occasionally small animals, but bamboo remains their staple. Their reliance on bamboo makes them vulnerable to habitat loss, as the survival of their population is directly linked to the availability of this specific food source.
