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.
Behavioral adaptation is when the living organism acts a certain way to survive, it does not change the body outlook but it allows for the creature to act a certain way to scare off predators or other things. Behavioral = the way it acts in its habitat. Structural = the way it changes its body to fit the habitat. Ex. An insect that has spikes on its body is a structural adaptation, because its body layout changed. An insect that plays dead is a behavioral adaptation because it acts like it is dead, it did NOT change its body layout.
