  1. Symbiotic Relationships

  2. Symbiotic Relationship • Objective: • 1,7

  3. Symbiotic Relationships • Journal: • Describe a close relationship you have with someone. Why do you consider it a close relationship? Explain.

  4. Symbiotic Relationships • Symbiotic Relationship: The interaction between individuals from two species that live closely together

  5. Symbiotic Relationships Point: Elements of any ecological system live in an intricate web of interdependence. When two species of organisms live in close physical contact with each other, their relationship is called “symbiotic.”

  6. Symbiotic Relationships Parasitism: A relationship between two species in which one species is harmed while the other benefits.

  7. Human Parasitic Examples • Botfly (humans) • Tapeworm (humans) • Fleas (humans) • Mosquitos (humans)

  8. Parasitic Example: • Wasp (caterpillar) • Jewel Wasps (paralyzes cockroaches, eggs laid on it’s body, hatch and eat the living host) • Phorid Flies (lay eggs in ants)

  9. Symbiotic Relationships • Parasitism Examples Mites: • Mites parasitizing a harvestman. • Mites can attack honey bees • Mites attack humans • Mites attack beetles

  10. Dog Parasites • Fleas • Ticks • Heartworms • Ear Mites • Tapeworms

  11. Symbiotic Relationships Mutualism: An interaction between two species in which both benefit.

  12. Symbiotic Relationships • Mutualism Examples: A remarkable 3-way mutualism appears to have evolved between an ant, a butterfly caterpillar, and an acacia in the American southwest. The caterpillars have nectar organs which the ants drink from, and the acacia tolerates the feeding caterpillars. The ants appear to provide some protection for both plant and caterpillar.

  13. Symbiotic Relationships • Meat Ants harvest Leaf Hoppers for their honey dew. The ants get an energy rich food source and the Leaf Hoppers receive protection from predators.

  14. Mutualism • Orchids and fungus Mycorrhizae • Fungus grows on root to help orchid get nutrients • Fungus gets some food from plant photosynthesis

  15. Mutualism • Fruit and Fruit eating birds • Fruit provides nutrients to bird • Fruit gets get dispersed

  16. Mutualism • Protozoa and termites • Protozoa live in the gut of termites • Termites would be unable to digest cellulose and wood • Protozoa get food and shelter and a mode of dispersal

  17. Symbiotic Relationships Commensalism: An interaction between two species in which one species benefits without harming the other.

  18. Commensalism • Barnacles on whales • They don’t seem to hurt whales • And in return get a habitat.

  19. Commensalism • Remora sharks • Gets a ride by attaching to other creatures • And gets the slop from the ride’s leftovers.

  20. Symbiotic Relationships • Common Clownfish (Amphiprion ocellaris) in their Ritteri sea anemone (Heteractis magnifica) home. As the fish benefits and the anemone is unaffected, this relationship is an example of commensalism. If the sea anemone gets food from the clown fish then it would be mutualism.

  21. Commensalism • Cattle Egret • Forages in fields and pastures. • The cattle stir up insects • The egret benefits, the cattle get nothing in return.

  22. Symbiotic Relationships Good Buddies Research Paper • You will give a short presentation to the class on your organisms. • It can be in a powerpoint format or just a report. • You must include pictures of your organisms.

  23. Symbiotic Relationships Good Buddies Research Paper Underlining Questions you must answer in your presentation: • Why do we live together? • What kind of symbiotic relationship do you have? Why? • What advantages and disadvantages do we provide one another? • What would happen if one of us weren’t here?
