3. Mutualism-both species benefit Commensalism- one species benefits, the other is unaffected Parasitism- one species benefits, the other is harmed THREE TYPES OF SYMBIOSIS

4. Both organisms benefit from the relationship. ‘ Win-Win ’ MUTUALISM The otters help the kelp by eating the sea urchins which endanger it. The kelp provides and anchor for the otters while they sleep. Otters and Kelp __________________________________________________________

5. Lichen is really two organisms: algae and fungus. The fungus needs food but cannot make it. The algae makes food but needs some way to keep moist. The fungus forms a crust around the algae which holds in moisture. Both organisms benefit. LICHEN

6. The tree-pies 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. THE CHITAL AND THE TREE- PIE

7. MUTUALISM Raccoon and Poison Ivy The raccoon eats the berries of the poison ivy and disperses the seeds as it poops. Both benefit.

8. MUTUALISM Black-eyed Susan gets pollinated by Green lacewing. Both benefit…lacewing gets food (nectar) and Black-eyed Susan gets pollinated.

9. MUTUALISM Mushroom and Fly Fly lands on and eats mushroom. Some of the spores will adhere to the fly. When the fly dies, (of natural causes) the spores will be on new ground and will allow the mushroom to grow in a new area.

10. 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. CLEANER FISH AND THE MORAY EEL

11. Each type of Yucca plant can only be pollinated by a specific kind of Yucca moth. That moth can only live on that kind of Yucca. YUCCA PLANTS AND YUCCA MOTHS

12. The tree provides a nursery for the ants in the thorns and makes special food for the ant babies. In return the ants sting and attack any other plants or insects that try to invade the tree. SWOLLEN THORN ACACIA TREE AND ANTS

13. One organism benefits, the other one is unaffected. ‘Win-Neutral Relationship’ COMMENSALISM 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. The cattle egret and cows __________________________________________________________

14. 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. BARNACLES AND WHALES

15. COMMENSALISM Red Maple and Eastern Bluebird Bluebird nests in the maple. Maple is unaffected, bluebird benefits

16. Pear-shaped puffball gets opened (and spores dispersed) by Opossum Puffball benefits, opossum is not affected. COMMENSALISM

17. The oak gall wasp stings the oak tree. the tree then grows a GALL which is a nest for the wasp ’ s babies. When the larva hatch, they eat their way out of the gall. Does not help or hurt the oak tree OAK GALL WASPS AND OAK TREES

18. British soldier lichen provides shelter for centipede. COMMENSALISM

19. 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! PARASITISM 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. __________________________________________________________

20. 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. BEDBUGS

21. The definitive host of the cucumber tapeworm is a dog or a cat (occasionally a human). Fleas and lice are the intermediate host. the dog or cat becomes contaminated when the eggs are passed in the feces, and the flea or louse ingests the eggs. The dog or cat (or human) is infected when they ingest a flea or louse. Hence the importance of controlling fleas on your pet! TAPEWORMS

22. Chigger lives and eats away at hognose snake. PARASITISM

23. Bullfrog acts as a host of the big red worm parasite. PARASITISM

24. Dogwood tree is parasitized by honeysuckle.

25. Mutualism, Commensalism, Parasitism WHICH TYPE OF SYMBIOSIS IS IT? Fleas/Dogs Lice/Humans Clownfish/Sea Anemone Crocodile Bird/Crocodile Joshua Tree/Pronuba Moth
