Presentation Transcript

  1. Taxonomy Presentation

  2. Kingdoms • Plants • Animals • Protists • Fungi • Archaebacteria • Eubacteria

  3. Kingdom Animalia • Porifera • Cnidaria • Playhelminthes • Nematoda • Mollusca • Annelida • Arthropoda • Echinodermata • Chordata

  4. Body Plans: • Asymmetry: no symmetry ex. Porifera (sponges) • Radial Symmentry: cut anywhere in plane and symmetrical. ex. Volvox • Bilaterial Symmetry: mirror images halves. ex. butterfly

  5. Feeding Strategies • Autotrophor Heterotroph

  6. Autotroph: • Can produce own food: Photosynthesis

  7. Heterotroph • Cannot produce own food • Examples: • grazer 2. predator 3. scavenger 4. parasite 5. decomposer 6. filter feeder

  8. Symbiotic Relationships • Parasitic: one organism is harmed and the other benefits • ex mosquito/human • Commensalism: one organism doesn’t get helped or harmed but the other benefits • ex. Shark/remora • Mutalism: both organisms benefit • ex. Oxpecker and rhino

  9. Reproduction • 1. Sexual: external or internal fertilization • 2 . Asexual: offspring arise from singe parent • Monoecious: each individual produces both egg and sperm • Dioecious: each individual produces either egg or sperm but not both.

  10. Plankton and Detritus • Detritus: ODRSAP • Old, dead rotten stuff and poo • 2. Plankton: live in water, “carried by the current”- member of at least three kingdoms, protists, animals, and plants.

  11. Phytoplankton/zooplankton • Phytoplankton: mostly protists and photosynthesize • Zooplankton: protists and animal • Larval state of almost all invertebrates, some fish • Organisms which remain plankton • Ex. Krill: feed many large aquatic animals • Ex: copepods: extremely important to ocean life food web
