- adaptations
- structural adapations
- defintion
- features of an organisms body such as shape or colour that suits it to its environment
- example
- camels
- thick lips for protection when eating things such as cacti
- humps storing fat and water in case they cant find any food or water for a long time
- thick foot pads to protect from the hot sand
- camels
- defintion
- extremophiles
- example
- the aquifex type of bacteria which is adapted to survive in a range of extreme conditions including extreme temperature, acidic environments,salty environments or places without oxygen
- definition
- organism which is adapted to live in an extreme environment
- types of extremophile
- thermophiles
- definition
- organisms that can survive in extreme heat
- definition
- xerophiles
- definition
- organisms that can survive in environments with minimal water
- example
- cacti
- have spines instead of leaves to decrease transpiration and hold in water
- have a waxy skin to hold in water
- have extensive and complex root systems to get as much water as possible from underground
- cacti
- definition
- thermophiles
- example
- functional adaptations
- defintion
- the things that go on inside the body of an organism that can be related to processes such as reproduction and metabolism
- example
- brown bear
- heart rate and body temperature drop during hibernation to conserve food and energy
- build up a large amount of body fat in winter before hibernation which creates a store of energy and helps keep them warm
- brown bear
- defintion
- behavioural adaptations
- defintion
- the ways an organism behaves which suit it to its environment and help it survive and reproduce
- example
- meerkats
- dig burrows to sleep in and hide from predators
- form families of 20 to 50 to share jobs and responsibility - eg: have a meerkat on guard duty to look for predators
- meerkats
- defintion
- mimicry
- defintion
- when one species looks similar to another species
- example
- when a butterfly mimics the patterns of a butterfly with a bitter taste to make predators think it also has a bitter taste
- defintion
- definition
- changes in an organism or species physical structure, function or behaviour which allow it to survive and reproduce
- structural adapations
