Year 11 Adaptations

Adaptations are ​ (a)   that have evolved over ​ (b)   years in response to various ​ (c)   factors. Adaptations help organisms ​ (d)   in a ​ (e)   environment.

• features
• many
• environmental
• specific
• survive
• few
• genetic
• thrive
• harsh

Define structural adapations

• physical characteristics / features that help organism survive

• bodily process and organs that help organism survive

• actions that organism takes to help them survive

Define physiological adapations

• physical characteristics / features that help organism survive

• bodily process and organs that help organism survive

• actions that organism takes to help them survive

Define behavioural adapations

• physical characteristics / features that help organism survive

• bodily process and organs that help organism survive

• actions that organism takes to help them survive
