ANIMAL ADAPTATIONSDifferent conditions:- Desert- Tropical Grassland (Savannah)- Rock deserts and sparse grasslands- Arctic conditions

DESERT CONDITIONS2 Main Adaptations• Lack of Water• Extremes in temperature

Water• Where from????• How do they prevent water leaving there bodies????

- Habitat- Body design

Examples of Animal Adaptations (Desert)Fennec Fox• Large ears• Kidneys• Habitat & Lifestyle• Thick and sandy coloured Fur

Desert tortoise• Lifestyle• Habitat• Survive for ONE YEAR without water• Shell for protection• Shallow pits for catching rain

TROPICAL GRASSLAND (SAVANNAH)

Predators• Fast, alert, powerful and smart to catch Prey - Cheetahs

- Lions- Hyenas

SO WHAT ADAPTATIONS ARE IMPORTANTFOR THEM????

Lions• Loose belly skin• Mane (male lions)• Position of eyes• Muscled forearms & shoulders• Retractable claws• Rough tongue• Sandy colour

ROCK DESERT & SPARSE GRASSLANDS

Lizards & Leopard Gecko• Tail that breaks off (avoidance of predators)• Disadvantage of tail loss• Lifestyle (Nocturnal)• Body adaptations

ARCTIC CONDITIONSCold, snowy conditions

Polar Bear• Colour?• How do they keep warm?• Size and shape of paws?• NostrilsPenguins• All penguins in Southern Hemisphere• Flightless but good swimmers• How are they adapted for swimming?• How do they keep warm? (Body and behaviour adaptations)• Why feathers?•How do they stay underwater?

PLANT ADAPTATIONSPlants need water OR they will die

Mesophytes – no specific adaptationsHydrophytes – adaptations for living in waterXerophytes – adaptations for living in dry conditions

XEROPHYTESLow rainfall and high temperatures

Modifications• Succulents store water in times of plenty• Stomata on lower side of leaf (reduces transpiration)• Some leaves die and wither• Thick cuticle• Hairs on leaf• Folding of leaves• Compound leaves• Leaf arrangement (for shade)• Root systems deep

HYDROPHYTESFound living in and around rivers, lagoons etc…..

Modifications• Large flat leaves that float• Leaves have notches or hairs• Long, flexible stalks• Shallow underground stem •(rhizome) & small rootsExamples• damp soil, edge of water e.g. bulrushes• shallow water, roots in mud e.g. water lily• float on surface e.g. water hyacinth• totally submerged except floating flowers e.g. ribbon weed
