The primary diet of a frugivore consists mainly of fruits. Frugivores are animals that have evolved to consume a diet rich in fruits as their primary source of nutrition, often supplemented by leaves or nectar. This dietary preference is common among various species, including some primates, birds, and bats. Frugivores play a critical role in their ecosystems by aiding seed dispersal, which is vital for the reproduction of many plant species. This mutualistic relationship helps maintain biodiversity and supports the health of their habitats.
