Why do some animals have sharp teeth?

Sharp teeth are an adaptation for many animals to help them capture and consume prey. Carnivorous animals, such as tigers and sharks, have sharp teeth designed for tearing flesh and breaking bones. Herbivores, like rodents, have sharp incisors that allow them to gnaw on tough plant material. Some omnivorous animals, like bears, have a mix of sharp teeth for eating meat and flat molars for grinding plants. Sharp teeth are essential tools that allow these animals to exploit specific food sources effectively.
