Answer 2

When objects move through fluids, they have to overcome the friction acting on them, due to which they lose energy. So, efforts are made to minimize the friction. For this, the objects are given special shapes. As we know, birds and fishes have to move about in fluids all the time. Their bodies must have evolved to shapes which would make them lose less energy in overcoming friction. Such shapes are called streamlined shapes. This is the reason ships and aeroplanes are given a streamlined shapes so that minimum energy is lost while moving through water and air respectively.
