Study Notes

Animal Classifications

  • Four animal classifications: Cold-blooded, Warm-blooded, Vertebrates, Invertebrates
  • Cold-blooded animals are also known as ectotherms.
  • Warm-blooded animals are also known as endotherms.
  • Animals active during the day are diurnal, animals active during the night are nocturnal, and animals active during dusk to dawn are crepuscular.
  • Animals with backbone are vertebrates, animals without backbone are invertebrates.

Benefits of Vertebrates and Invertebrates

  • Vertebrates benefit from having a strong internal structure, which provides support and allows for movement and protection for internal organs.
  • Invertebrates benefit from being able to adapt to various environments due to their small size and diverse body structures.

Adaptation and Evolution

  • Adaptation is the process by which an organism changes in response to its environment to survive and thrive.
  • Examples of adaptation:
    • Polar bear: Thick fur and blubber to survive in cold Arctic climates
    • Desert fox: Large ears to lose heat in hot desert environments
    • Camel: Can store water in its hump to survive in arid environments
  • Evolution is the gradual change in the genetic makeup of a species over generations.
  • Evolution occurs as species adapt to changes in their environment and compete for resources.
