Animal and plant adaptations and behaviours. Adaptations help organisms survive in their ecological niche or habitat; adaptations can be anatomical, behavioural or physiological. Anatomical adaptations are physical features such as an animals shape. Behavioural adaptations can be inherited or learnt and include tool use, language and swarming behaviour. Physiological adaptations include the ability to make venom; but also more general functions such as temperature regulation.
basically what an animal does to survive in the habitat. Behavioral adaptations are different to physical adaptations because behavioral adaptations are (like the name suggests) changes in behavior that increase an organisms fitness/survival, whereas physical adaptations are changes to an organisms body structures.
