Adaptation
a feature or behaviour that increases an organism's chance of survival
two types
Structuralphysical features — body covering, colour, shape
Behaviouralspecial behaviours — migration, hibernation, hunting in packs
coping with living factors
Predator–preycamouflage · eyespots · toxins · eyes at the side of the head · living in groups · intimidation
Obtaining foodacute senses · venom · specialised mouths, teeth and feet · hunting in packs · traps and tools
Defence in plantsneedle-like leaves · stinging or fine hairs · nectaries · leaf spots
Reproduction & youngbright colours · pheromones · mating dances and calls · parental care · many eggs
if it cannot adapt
The organism must leave its habitat or risk dying out
cold and heat
Coldthick fur · blubber · small ears · hibernation · huddling together
Hotlarge ears · long legs · burrowing · aestivation
too little water
Animalsreduced sweating, so less water is lost
Plantsdeep roots · water-storing stems · spines instead of leaves · a waxy cuticle
light and movement
Lighttendrils · clasping roots · twining stems · epiphytes growing on other plants
Moving in waterstreamlined body · fins · flippers · webbed feet · strong tails
water and air
Wet placeswaxy floating leaves · breathing roots · waterproof fur
Air on landgill chambers and moist skin for animals that spend time out of water
Oxygen in waterblowholes · breathing tubes · carrying air bubbles down
