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 IMPORTANT

FOR 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

conditionsPolar 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 adaptations

Hydrophytes – adaptations for living in water

Xerophytes – 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 roots

Examples

• 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
