O How does a streamlined body help in the
movement of animals that fly or swim?
Answers
Answer:
Streamlined body means body which can offer minimum resistance to air and water by its particular type of body shape. Streamlined body helps bird to fly easily in air by reducing resistance by air and in case of aquatic animals, streamlined body helps to swim easily through water by reducing resistance by water.
Answer:
Streamlined shaped body is that body whose shape is narrow at the ends and broader at the middle.
This type of shape is commonly found in aquatic animals and aves (the one who fly).
This type of shape enables them to reduce the friction as well as enables them to apply more pressure and move swiftly through air or water.
As we know that Pressure is inversely proportional to area of contact and as the area of contact of animals who have streamlined shape is less so they are able to apply more thrust (perpendicular force) in water or air that makes their movement easy.
So in these ways the streamlined shape of aquatic animals and those who fly in air help them to move easily.
