1. Symbiosis

2. Symbiosis
Any two organisms that interact in close proximity to one another
Comes from the Greek SYM- which means together, and BIO- which means life

3. Five Types of Symbiosis
Mutualism
both species benefit
Commensalism
  one species benefits, the other is unaffected
Parasitism
  one species benefits, the other is harmed
Competition
species compete for resources; both are harmed
Predator/Prey
one species consumes another

4. Mutualism Both organisms benefit from the relationship Otters and Kelp
The otters help the kelp by eating the sea urchins which endanger it. The kelp provides an anchor for the otters while they sleep.

5. 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.

6. Commensalism One species benefits while the other is uneffected
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 flies. This does not effect the cattle in any way.

7. 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.

8. Parasitism One species benefits while the other is harmed
Mistletoe is an aerial parasite that has no roots of its own and lives off the tree that it attaches itself to. Without that tree it would die. It slowly chokes out the life of the host tree.

9. Bedbugs
Bedbugs are small, nocturnal parasites that come out of hiding at night to feed on unsuspecting humans.  They feed exclusively on blood!  Their bites often result in an allergic reaction.

10. Competition
Both species compete over resources such as food, water, or mates
Male Red deer will fight during mating season for the right to mate with the female deer

11. Zebra and Gazelle
Zebra and gazelle compete over food resources by eating the same grass in the African Savannah

12. Predator/Prey Lions hunt and consume wildebeest for food
One species consumes another
Lions hunt and consume wildebeest for food

13. Eagle and Fish
Bald eagles dive down and scoop up various fish using their talons
