Question

How are streamlining of the body of the fish achieved.

Answer 1

Friction produced by fluids are known as drag.Water produces drag.As fish is an aquatic animal,it should overcome drag.Streamlining is one of the better methods that reduces friction.A streamlined body is sharp at the front and rounded at the back.Thus the streamlined body of a fish helps the fish to reduce the drag and to move easily and faster through water.
