What is the most important part of an orang-outangs diet?

The most important part of an orangutan's diet is fruit, particularly tropical fruits like figs, which are abundant in their natural habitat. They also consume leaves, flowers, and bark, but fruit provides the majority of their energy and nutrients. Due to their slow metabolism and the need for a rich source of calories, orangutans primarily rely on the availability of seasonal fruits in their rainforest environment. Their diet plays a crucial role in their health and the ecosystem, as they help disperse seeds through their feeding habits.
