Adaptation

Adaptation

1. Adaption=successful living in a habitat

2. Types

   • Camoflague
     • e.g. Chamaeleons-when a creature change its skin colour and colour patterns to blend in with the environment.
   • Structural
     • Physical features e.g. fur on a bear.
   • Physological
     • Organs peform specialy
   • Behavioral
     • How a creature behaves e.g. bird calls

3. Camel Adaptation

   • Thick lips-eat cacti, hump with fat to break to glucose-water in respiration, big feet-traction, ling eyelashes-sandstorms, body temperature regulates, ears lined with fur-sand, nostrils can close.

4. Polar bear adaptation

   • Black skin-absorbs heat, sharp teeth, large feet-not much pressure, thick fur, ears lay flat on head whilst swimming, claws, good vision, fur-camoflague.

5. Plant adaptation

   • Cacti adaptation-hot climate
     • Stems that can store water. Widespread root systems that can collect water from a large area. cacti have spines instead of leaves. These minimise the surface area and so reduce water loss by transpiration. The spines also protect the cacti from animals that might eat them.
   • Cold climate plants
     • Small plants and shallow root systems compensate for the thin layer of soil, and small leaves minimize the amount of water lost through the leaf surface. Plants grow close to the ground and to each other, this helps to resist the effects of cold weather and reduce damage caused by wind-blown snow and ice particles. Fuzzy coverings on stems, leaves, and buds and woolly seed covers provide additional protection from the wind.

6. Competition

   • Plant
     • Plants fight for soil minerals, water and vitamins. They also fight for light.
   • Animal
     • Animals fight for food and prey and for mates.
