  1. ANIMAL ADAPTATIONS • Different conditions: • Desert • Tropical Grassland (Savannah) • Rock deserts and sparse grasslands • Arctic conditions

  2. DESERT CONDITIONS • 2 Main Adaptations • Lack of Water • Extremes in temperature • Water • Where from???? • How do they prevent water leaving there bodies???? • - Habitat • - Body design

  3. 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

  4. TROPICAL GRASSLAND (SAVANNAH) • Predators • Fast, alert, powerful and smart to catch Prey • - Cheetahs • - Lions • - Hyenas • SO WHAT ADAPTATIONS • ARE IMPORTANT • FOR THEM????

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

  6. ROCK DESERT & SPARSE GRASSLANDS • Lizards & Leopard Gecko • Tail that breaks off (avoidance • of predators) • Disadvantage of tail loss • Lifestyle (Nocturnal) • Body adaptations

  7. ARCTIC CONDITIONS Cold, snowy conditions • Polar Bear • Colour? • How do they keep warm? • Size and shape of paws? • Nostrils • Penguins • 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?

  8. PLANT ADAPTATIONS Plants need water OR they will die Mesophytes – no specific adaptations Hydrophytes – adaptations for living in water Xerophytes – adaptations for living in dry conditions

  9. XEROPHYTES • Low 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

  10. HYDROPHYTES • Found 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
