  1. Adaptation www.assignmentpoint.com

  2. What is adaptation? • Adaptation describes how a plant of animal is able to survive in various environments • Well adapted organisms can cope with the different aspects of their environment, for example, the temperature www.assignmentpoint.com

  3. ANIMALS STRUGGLE : For food For water For protection against weather Against being eaten by predators Against disease Against accidents PLANTS STRUGGLE: For water For light For minerals in the soil Against weather Against disease Against being eaten It is always a struggle for plants and animals to survive www.assignmentpoint.com

  4. How does adaptation help organisms? • Well adapted organisms are better at coping with extremes of weather • They are better at competing for food • They are better at escaping from predators • They are more likely to survive in their habitat and produce offspring www.assignmentpoint.com

  5. An arctic habitat • This sort of habitat can have extremely low temperatures • The ground is covered with white snow for most of the year www.assignmentpoint.com

  6. How are animals adapted to survive in the Arctic? • Animals like polar bears will have a thick insulating coat • They usually have a large amount of body fat • They have a large body size to surface area ratio • They have a camouflaged coat www.assignmentpoint.com

  7. A thick fur coat Large body size to surface area ratio A large amount of body fat Camouflage Traps heat to keep warm Reduces heat loss by radiation Acts as a food store and to keep warm White fur is good camouflage to hide from prey How do these adaptations help? www.assignmentpoint.com

  8. A desert environment • A desert can have very little rainfall • There is a lot of sunshine during the day • There is very little shade • The temperatures can get very hot • At night it can become very cold www.assignmentpoint.com

  9. How is a camel adapted to survive in the desert? • Camels can store large amounts of water in the fat in their humps • They have feet with a large surface area to allow them to walk on sand • They also have long eye-lashes to stop sand blowing into their eyes www.assignmentpoint.com

  10. How do reptiles survive in the desert? • Most reptiles will find some shade under a rock during the hottest part of the day • When walking on hot sand a lizard will try to touch the ground with only a small area • This lizard keeps swopping feet, and only stands on two feet at a time • This snake keeps a loop of itself off the ground as it moves across the sand sideways www.assignmentpoint.com

  11. How do plants survive the desert? • A cactus has a long tap root to reach water deep under the ground • It has a thick, fleshy stem to store water • It has needle-shaped leaves to prevent water loss through the stomata • The needles help to stop animals from eating it www.assignmentpoint.com
