  1. G.O.1 Biological diversity is reflected in the variety of life on Earth.

  2. Biodiversity • What does diversity mean? How can we represent “diversity” in a group of students? • “Biodiversity”, or “biological diversity”, refers to all living organisms on the earth. • Definition for organism = an organism is any contiguouslivingsystem (such as animal, fungus, micro-organism, or plant). In at least some form, all types of organisms are capable of response to stimuli, reproduction, growth and development, and maintenance of homeostasis as a stable whole. • Scientists study biodiversity in small groupings in order to track changes. • Why would they want to track changes? • What type of change would they track? • What could be done to minimize these changes?

  3. “Why do we have to learn this” • We’re all connected • http://www.youtube.com/watch?v=9laQwaKOW8s • Think about every action you have taken today…how many organisms were influenced or required for those actions to take place? Make a list…

  4. WHAT CHARACTERISTICS DO ALL LIVING THINGS HAVE IN COMMON • All living things have the following in common. They are: • Made up of cells • Need energy • grow and develop • Reproduce • Have adaptations to help them survive

  5. What is a Species? • A species is a particular group of organisms that have the same structure and can reproduce with each other. • Of the 30 - 100 million possible different species of living things, there are over 1.5 million species of animals and 350.000 species of plants that have been identified by biologists. • The most successful life form seems to be the insect.

  6. What is an ecosystem? • An ecosystem refers to all the animals and plants found in one place, and the way they all live together. • Different plants and animals live in different ecosystems. • Different ecosystems can be close together. • Some animals belong to several ecosystems.

  7. What are the Components Earth’s biodiversity? Components of biodiversity: • Genetic diversity – genetic variation within Genius or species • Species diversity – numbers of species within an ecosystem • Diversity among higher taxa – variation between genera, families, orders, etc. • Ecosystem diversity – variation among ecosystems, communities, landscapes Are different groups of organisms equally diverse? Are different parts of the world equally diverse?

  8. How does diversity change as you move from the north and south poles towards the Equator?

  9. There is _________________________________ biodiversity in the northern Arctic region because _____________________________________________________________________________________________________. There is _____________________ biodiversity in the equatorial regions because ______________________ _____________________ _____________________ _____________________ _____________________ There is _____________________________ biodiversity in the southern Antarctic region because _______________________________________________________________________________________________________.

  10. Biological Diversity Classification • The science of classifying organisms is called taxonomy • The “father of modern taxonomy” was Carolus Linnaeus (Carl von Linné) • Organisms are grouped into “taxa” based on their similarities to each other 1707-1778

  11. 5 Kingdom Classification System: • Monera: all prokaryotes (bacteria) • Protista: single-celled eukaryotes (protists) • Fungi: multi-cellular heterotrophic sessile eukaryotes • Plantae: multi-cellular autotrophic sessile eukaryotes • Animalia: multi-cellular heterotrophic motile eukaryotes

  12. Classifying Organisms • Kingdom • Phylum (& Subphyla) • Class • Order • Family • Genus • Species • Come up with your own mnuemonic

  13. Human Classification • Kingdom – Animalia • Phylum – Chordata • Class – Mammalia • Order – Primates • Family – Hominidae • Genus – Homo • Species - sapien

  14. Classifying cousins…booklet pg 15 • Kingdom: Animalia • Phylum: Chordata • Class: Mammalia • Order: Carnivora • Family: Canidae • Genus: Canis • Species: C. lupus • Kingdom: Animalia • Phylum: Chordata • Class: Mammalia • Order: Carnivora • Family: Canidae • Genus: Canis • Species: Canis lycaon

  15. Which species are most related? • Members of the Rosaceae family: • Rosa arvensis • Rubusarcticis • Members of the Iridaceae family. • Iris germanica • Iris persica
