Introduction to Adaptations

Types of Adaptations

This post will be an introduction to adaptions and will go through the types of adaptions that exist for Prelim Biology.

Topic: Adaptations

  • Conduct practical investigations, individually or in teams, or use secondary sources to examine the adaptations of organisms that increase their ability to survive in their environment, including:
    • Structural adaptations
    • Physiological adaptations
    • Behavioural adaptations

 

What Are Adaptations?

While you may associate adapting with quickly changing to a new situation, such as adapting to a new phone or schedule, in biology, an adaptation is a change that has occurred over many many hundreds, thousands or millions of years that has resulted in an organism being better suited for their environment.

There are three main types of adaptations:

  • Structural – to do with physical attributes (e.g. Some plants have big leaves to get more sunlight)
  • Physiological – to do with internal chemical attributes (e.g. snakes produce venom for protection)
  • Behavioural – to do with the interactions of organisms within their own species or other species (e.g. penguins huddle to conserve warmth)

This video will take you through the types of adaptations.

 

This video will take you through a little more with some examples.
