  1. Symbiotic Relationships and Metamorphosis By: Brianna Shields November 1, 2004

  2. DO NOW • Please lay your ecology flashcards out on your desk ( 4 across x 5 down) with the definition side up. • Once I’ve checked yours, take turns working with your seat partner to learn the terms on your flashcards.

  3. GOAL • To distinguish developmental patterns found in various animals (Metamorphosis) • To compare several symbiotic relationships

  4. Symbiosis 1. Close relationship between two organisms 2. One lives near, on or in the other Symbiosis

  5. Commensalism One organism benefits and the other is not effected Ex: 1. Tiny mites living on human eyebrows Symbiosis

  6. Eyebrow Mites

  7. Mutualism Both organisms benefit Ex: 1. Bacteria in the human digestive system Symbiosis

  8. Microbes in Human Gut

  9. Parasitism One organism benefits, the other is harmed Ex: Dog fleas Symbiosis

  10. What type of symbiosis is this? • Ruminants in cow gut, digest the hay/plant material. Cow food gets digested, ruminants get a meal MUTUALISM

  11. What type of symbiosis is this? • Egyptian Plover removes parasitic insects from the backs of horses and cattle MUTUALISM

  12. What type of symbiosis is this? • Mosquitoes on humans PARASITISM

  13. What type of symbiosis is this? • Barnacles on the backs of crabs are fed as the crab moves through the water- but, the crab is left unaffected Commensalism

  14. What type of symbiosis is this? • Remora fish attach themselves by suckers to sharks. This allows them to filter in food while the shark swims- this relationship has no apparent effect on the shark Commensalism

  15. What type of symbiosis is this? • The Yucca Moth obtains food from the Yucca plant- while in return carries pollen from plant to plant for reproduction Mutualism

  16. What type of symbiosis is this? Parasitism

  17. Complete Metamorphosis 1. Fast, drastic changes in the form of an organism 2. Appearance looks totally different in each stage 3. Ex: Butterfly, Ladybug, Frog Life Cycles

  18. Butterfly Life Cycle

  19. 1. Laid under leaves 2. Caterpillar actively eats 4. Wings, bright colors sips liquids 3. Cocoon/ Chrysalis protects during development

  20. Ladybug Life Cycle

  21. 2. Long body, 6 legs, actively eats 1. Yellow rice masses laid on a leaf Ladybug 3. Pupa revealed when larva splits open 4. Mobile (moves a lot)

  22. 1. Egg masses laid in water 5. Adult- no tail, uses lungs 2. Tadpole/polliwog swims, eats, grows- has gills and tail 3. Tadpole with legs- sprouts arms and legs- has gills and tail 4. Froglet- has lungs, still has tail

  23. Frog Life Cycle

  24. Frog Life Cycle

  25. Incomplete Metamorphosis 1. Slow, gradual changes in the form of an organism 2. Appearance doesn’t really change- young resembles adult 3. Ex: Grasshopper Life Cycles

  26. 3. Adult- has wings, leaves water, moves well 2. Nymph- actively feeds on algae- stays in water 1. Egg on water surface or near water on plants

  27. What type of metamorphosis does this life cycle represent? Explain… Complete Metamorphosis

  28. What type of metamorphosis does this life cycle represent? Explain… Complete Metamorphosis

  29. What type of metamorphosis does this life cycle represent? Explain… Incomplete Metamorphosis

  30. What type of metamorphosis does this life cycle represent? Explain… Complete Metamorphosis

  31. What type of metamorphosis does this life cycle represent? Explain… Incomplete Metamorphosis

  32. What type of metamorphosis does this life cycle represent? Explain… Incomplete Metamorphosis Head Lice
