Question

Development of patagia in animals is
A)Aquatic adaptation
B)Arboreal adaptation
C)Cave adaptation
D)Volant adaptation

Answer 1

Hint: Patagia that is commonly termed as wings are the modifications that are observed in the birds that are largely useful for flying. Birds have to keep their body in mind and also, they are adapted for the propulsion.

Complete answer:
The animals that show presence of patagia or wings show Volant or flight adaptations. The patagia or wings are enclosed with light feathers that allow the body of the bird to become light in weight. This plays a role in the reduction of the weight of the organism at the time of flying. Birds are known for two adaptive modifications- one for the air and one for land.

For flying in the air, they establish a mechanism termed as the flight mechanism apart from the terrestrial or aquatic adaptation. The adaptation of animals in the air or the extra-terrestrial environment is termed as Volant adaptation. Volant adaptation is referred to as the adaptations that are done by the animals that spend most of their time in the air, i.e., flying. The environment, i.e., the air is characteristically homogeneous than any other habitats. There is less chances of friction with air during the movement of the birds. The only issue faced is the gravitational force of the earth. The animals that possess Volant adaptations have adapted flight mechanisms as their main instrument to overcome the gravitational force of the earth.

There are two types of flight that are observed in Volant animals:
1)Active flight - Some common examples of active flight birds include Tree frog, Draco, etc.
2)Passive flight - Some examples of passive flight birds include Eagle, vultures, etc.

Adaptation is referred to as the evolutionary process that fits organisms to their respective environments, thereby increasing the evolutionary fitness of the organism. Adaptation is extremely necessary for the organisms to survive. Animals that are not able to adapt to environmental changes die very easily.

Hence, the correct answer is option (D)
