  1. Symbiosis Living Together

  2. USE THIS POWERPOINT TO COMEPLETE YOUR symbiosis notes Using this PowerPoint, write the definition for each type of relationship(mutualism, commensalism & parasitism). Afterward, give two example for each type of relationship. Lastly, draw a sketch to represent each type of relationship. PLEASE NOTE: There are MORE THAN TWO examples for each relationship! YOU MUST ONLY CHOOSE TWO for your notes!

  3. Sym-bio-sis: a definition • Sym: From the greek/latin meaning “with” • Bio: from the greek/latin meaning “to live”or “living” • Symbiosis:A relationship where two organisms live together where at least one of the organisms benefits from the relationship.

  4. Three Types of Symbiosis • Mutualism-both species benefit • Commensalism- one species benefits, the other is unaffected • Parasitism- one species benefits, the other is harmed

  5. Mutualism • Both organisms benefit from the relationship. • ‘Win-Win’ Example #1: Otters and Kelp The otters help the kelp by eating the sea urchins which endanger it. The kelp provides and anchor for the otters while they sleep.

  6. Example #2: The Chital and the Tree-pie • The tree-pies (bird) help the chital by stripping the dead velvet from the antlers. This provides them with nourishment Therefore both species are benefiting from this symbiotic behavior.

  7. Mutualism • Example #3: Raccoon and Poison Ivy • The raccoon eats the berries of the poison ivy and disperses the seeds as it poops. • Both benefit.

  8. Example #4: Cleaner Fish and the Moray Eel • The cleaner fish eats parasites and food bits out of the inside of this moray eel. It gets a meal and is protected from predators by the fierce eel.

  9. Commensalism • One organism benefits, the other one is unaffected. • ‘Win-Neutral Relationship’ Example #1: The cattle egret and cows The cattle help the egret who look for grasshoppers and beetles that are raised by the cows. Now and then they sit on the back of a cow, looking for ticks and flies. This does not effect the cattle in any way.

  10. Example #2: Barnacles and Whales • Barnacles need a place to anchor. They must wait for food to come their way. Some barnacles hitch a ride on unsuspecting whales who deliver them to a food source. This does not effect the whale in any way.

  11. Commensalism • Example #3: Red Maple Tree and Eastern Bluebird • Eastern Bluebirdnests in the Red Maple Tree. • Maple is unaffected, bluebird benefits

  12. Commensalism • Example #4: British Soldier Lichen (plant)provides shelter for centipede.

  13. Parasitism • One organism benefits, the other one is negatively affected • ‘Win-Lose Relationship’ • Parasites rarely kill their hosts…it would require them to get another one! __________________________________________________________ Example #1: Chigger is a mite that lives and eats away at hognose snake.

  14. Example #2: Bedbugs • Bedbugs are small, nocturnal parasitic insects that come out of hiding at night to feed on the blood of unsuspecting humans and animals while they sleep.  Their bites often result in an allergic reaction.

  15. Parasitism • Example #3: Bullfrog acts as a host of the big red worm parasite.
