1.Nearly 90% of orangutans diet is composed of fruit. They eat more than 400 different plant varieties. Orangutans favor a fruit called durians. Durians are covered in sharp spines and have a pungent smell. Orangutans use a variety of tools and their powerful jaws to break into such fruits.
2. Although fruit comprises most of the orangutan's diet, they still require other nutrients as part of their daily intake. They receive a mixture of sugars and fats from fruit, carbohydrates from leaves, and protein from nuts.
3.As fruit—eating animals, orangutans are important propagators of tropical plants. Many fruit seedlings sprout only after having passed through an animal's digestive system. Therefore, orangutans have a vital ecological role as seed dispersers in their rainforest environment and affect forest.
