Elephants use their trunks for which of the following reasons?
To smell the air
Break the branches of the trees
The nose and the upper-lip of the elephant are joined to form the trunk. The trunk is very useful though it looks funny. It is raised high to smell the air, to break the branches of the tree, to suck the water and pour it into the mouth, to uproot the grass from the earth and put it into the mouth. Even if there is a small fruit lying on the ground, it's not difficult for the elephant to pick it up with the end of the trunk.
