  1. HABITAT AND ADAPTATION 4444

  2. HABITAT • THE SURROUNDINGS WHERE ORGANISMS LIVE IS CALLED A HABITAT. • HABITAT HAS GOT TWO COMPONENTS • BIOTIC • ABIOTIC PLANTS ANIMALS ROCKS SOIL WATER AIR

  3. HABITAT • TERRESTRIAL AQUATIC MOUNTAINS OCEANS GRASS LAND PONDS AND LAKES DESERT RIVERS

  4. ADAPTATION • Anything that helps an organism survive in its environment is an adaptation.  • It also refers to the ability of living things to adjust to different conditions within their environments. 

  5. DESERT

  6. ADAPTATIONS OF DESERT ANIMALS • camels have long legs Which helps to keep their bodies away from the heat of sand • They excrete small amount of urine • They do not sweat • Animals like snakes and lizards stay in burrows during day time to escape the heat • Fennec fox have long ears to cool itself.

  7. ADAPTATION OF DESERT PLANTS • Leaves modified to spines to reduce transpiration • Photosynthesis is carried out by stems • Stem covered with waxy layer, helps to retain water • Roots grow deep into the soil to absorb water

  8. Camels Long eyelashes Keeps sand from storms and glaring sun from camels eyes. Humps Camel can store a supply of water so it doesn’t have to stop to drink Long Legs Big, flat feet Enable camels to walk on the sand without sinking into it.

  9. ANIMALS FOUND IN DESERT

  10. MOUNTAIN REGIONS

  11. Who would live here?

  12. ADAPTATIONS OF PLANTS AND ANIMALS • Have thick skin or fur to protect from cold • Eg: yak, tiger, angora rabbit • Strong hoofs for running up rocky slopes • Eg: mountain goat • Cone shaped trees with sloping branches help snow to slide off easily • Needle like leaves • Cone shape of trees help to withstand strong winds

  13. GRASS LANDS

  14. ADAPTATIONS • PREDATOR • Ability to blend with the surroundings, eg: light brown color of lion • Eyes in front of face allow correct location of prey • PREY • Strong teeth for chewing hard plant stems • Long ears to hear movements of predator • Eyes on the sides of head allow to look in all directions • Great speed

  15. AQUATIC HABITATS • OCEANS • PONDS AND LAKES

  16. OCEANS

  17. ADAPTATIONS • Streamlined body • Gills to breathe dissolved oxygen in water • In mammals, nostrils located on the upper parts of their heads helps to breathe in air • Can stay under water for along time without breathing

  18. PONDS AND LAKES • PLANTS • Roots are reduced in size, main function is to hold the plant in place • Stems are hollow and light • Thin ribbon like leaves, allow water to flow over them without damaging them • Webbed feet as in duck and frog help in swimming • Stream lined body and fins in fishes help them to swim

  19. Looking at living things LIFE PROCESSES

  20. Living things • Although all living things look different from each other, they all have seven things in common. • These seven things are called life processes. • Something is only alive if it does all seven processes.

  21. THE SEVEN LIFE PROCESSES

  22. All living things move 1

  23. Animals move their whole bodies to get from one place to another. Plants turn towards the light and their roots grow down into the soil.

  24. All living thingsreproduce 2

  25. Animals have babies. New plants grow from seeds.

  26. All living things are sensitive 3

  27. All living things respond to changes. Living things notice changes in their surroundings and react to them. Eg. Plants grow towards the light. Eg. People react to the temperature around them.

  28. All living things neednutrition 4

  29. Food is used to provide energy. Green plants make their own food using sunlight. Animals eat plants or other animals.

  30. All living thingsexcrete 5

  31. Waste substances must be removed from the body. Plants and animals both need to get rid of waste gas and water.

  32. All living thingsrespire 6

  33. Plants and animals use the oxygen in the air to turn food into energy.

  34. All living thingsgrow 7

  35. Babies grow into adults. Seedlings grow into plants.

  36. The seven life processes 1 Move 2 Reproduce 3 Sensitive 4 Nutrition 5 Excrete 6 Respire 7 Grow

  37. Use the first letter from each process to help you remember them. Move Reproduce Sensitive Nutrition Excrete Respire Grow They spell MRS NERG

  38. This is MRS NERG ! Can you remember what each of the letters in her name stand for ?
