Functional Adaptations 

A functional adaption can be easily decribed as an automatic body function that does something without being told to. For example, the human heart begins to beat faster when exercising.

Some adaptations include: digesting food, making venom, secreating slime and being able to keep a constant body temperature. 

 

 

Structual Adaptations

A structual adaptaion is best described as a body part that developes over time to help the animal survive. For example, a ploar bear has thick fur to help stand the cold weather. This is an example of a structual adaptation. The animal has developed some form of body part to withstand the conditions of the enviroment.  

 

Behavoural Adaptations

A behavoural adaptaion can be explaied as an action an animal chooses to do. For example birds choose to migrate to the south every winter to escape the cold. However they fly back after the winter has passed, this is so the birds can always be in the warm weather.
