Hello,

Adaptations are special body parts or behaviors that help a living thing survive in an environment. There are two main types of adaptation: physical adaptations and behavioral adaptations.

Example :
Some examples include:The duck has webbed feet for propelling it through the water and strong wings to take to flight quickly.

Structural adaptations are physical features of an organism like the bill on a bird or the fur on a bear. Other adaptations are behavioral. Behavioral adaptations are the things organisms do to survive. For example, bird calls and migration are behavioral adaptations.

A physiological adaptation is something that allows an animal to survive. For example, a flower may originally be "fresh water" but if placed near the sea, may adapt to the salt water surrounding it. The flower would then make changes In It's body to help it survive and thrive in the salt water environment.

The definition of structural is something arranged in a specific way, or something that is strong enough for construction use. An example of structural is a Lego building set; a structural toy. An example of structural a two by four piece of redwood; structural redwood.

Hope it helps
Thank you !!!
