TRANSCRIPT
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
weed
