Final answer:
The statement that the diet of wild okapis consists entirely of foliage is true, as okapis are herbivores that are classified as folivores and primarily consume leaves and other plant matter.
Step-by-step explanation:
The diet of wild okapis is indeed focused on herbivory, as these animals are classified as folivores, which means that they primarily consume foliage, such as leaves from trees and bushes. Therefore, the statement that the diet of wild okapis consists entirely of foliage can be considered true. Okapis have a digestive system that has specifically evolved to breakdown and extract nutrients from plant material, a common trait among herbivores. While other herbivorous species, like deer, koalas, and certain bird species, may incorporate various types of plant materials into their diets, such as fruits, seeds, or nectar, okapis are largely folivorous in nature. In the wild, these animals will graze on tree leaves, twigs, fruits, ferns, and other plant matter available in their rainforest habitat. The variety of plant materials they consume helps them to get all the necessary nutrients to thrive.
