Answer 2

Answer:

The tusks of elephants are modified incisors

Explanation:

Generally tusks are the enlarged canines of the mammals. But in elephants, tusks are the enlarged second upper incisors which grow very large and long in size. They use them as weapons against predators. They also help in digging, stripping bark and many more. Tusk's other name is ivory.  For protection, attack, digging, moving objects, collecting food, and removing bark from trees, tusks are used. These often secure the delicate trunk. In times of drought, by using their tusks, feet and trunks, elephants dig water holes in dry riverbeds.
