Question

birds need to keep their body light to help in flying hence they show presence of some organs only on one side how their skeleton helps in reducing theor weight​

Answer 1

The bird skeleton is extremely lightweight, but strong enough to withstand the stresses that a bird experiences when taking off, flying, and landing. The bird's hollow bones make the skeleton lighter for flying, and allow more oxygen to be absorbed from the air into the blood for that extra energy a bird needs.
