  • When confronted with an unidentified species, scientists look at classification keys which give hints to help provide a name for it. Species in the same group usually share characteristics since they have descended from a common ancestor. Classification can be used to predict how they evolved. If several species in a group share a characteristic, another species in the group will probably share that characteristic.
  • Left - The Cook Strait giant weta, photographed by Brian Eting. Middle - The mountain stone weta occupies the crevices and cavities of rocks (45mm). Right - The giant scree weta lives in the scree of alpine areas (45mm). http://weta.boarsnest.net/gallery2.htm
  • Bacteria/ Blue-green Algae
  • Protists and Algae
  • Mold/ Yeast/ Mushroom Heterotroph - consume food (can’t make their own) Saprophytes - live off dead organic matter
  • Autotrophs - make own food Higher Plant
  • Sessile or motile Release of energy Respond to environment Increase in mass Increase in organisms Get rid of metabolic waste Take in building blocks of life
  • building up or breaking down chemical reactions in the body ability to maintain a balanced system despite fluctuations in environment inherited characteristics that enable survival and reproduction in a habitat opportunities provided by habitat, adaptations to make the most of it

    1. 1. Ecology
    2. 2. What is Classification <ul><li>arranging living organisms into groups based on similarities in structure, embryology, and DNA. </li></ul>
    3. 3. Why Classify Organisms <ul><li>Aiding the identification of species </li></ul><ul><li>Shows evolutionary links </li></ul><ul><li>Predicting characteristics shared by similar species </li></ul>
    4. 4. Species <ul><li>a group of organisms with similar characteristics </li></ul><ul><li>can interbreed and produce fertile offspring. </li></ul><ul><li>DNA will also be very similar. </li></ul>
