Summary Introduction

To determine:

The adaptation of the bird’s skeleton flight.

Introduction:

The animals perform different functions and have different structural organization. These structural organization, helps in the survival of the organism. The birds, which are adapted to flight have their body designed in such a way that they can lift their weight to fly in the sky.

Explanation of Solution

The given adaptation of the skeleton system of birds help in their flights.

1. They have hollow and light bones, which reduces their weight, so, making the body easy to lift.
2. The sternum is keel shaped that provide a streamlined body, helping in reducing the viscosity of the air.
3. The bones of the birds are less in number, which reduces the weight further.
