- Scavengers: Cleaning up carcasses and preventing the spread of disease.
- Seed Dispersers: Contributing to plant regeneration through their droppings.
Conclusion
Bears exemplify the versatility of the Carnivora order, thriving as omnivores in diverse habitats. Their ability to consume a wide range of foods—from plants to meat—highlights their ecological importance and adaptability.
