Describe specializations like frugivores and folivores

Among herbivores, some groups show special adaptations based on specific plant parts they consume:

• Frugivores: Animals that primarily eat fruits. Examples include fruit bats, hornbills, and orangutans. They have strong jaws and sensitive taste buds to detect ripeness. Frugivores aid seed dispersal, helping in forest regeneration.
• Folivores: These feed mainly on leaves — examples are koalas, sloths, and pandas. They possess large molars, a slow metabolism, and gut microbes that break down tough cellulose.
• Other examples include nectarivores (feeding on nectar, e.g., hummingbirds) and granivores (seed eaters, e.g., pigeons and squirrels).

Such dietary specialisations demonstrate how herbivores diversify to occupy distinct ecological niches within ecosystems.
