Symbiotic Relationships

1. Mutualism: both organisms benefit from the relationship
Example: Flower Dogwood & Carpenter Bees (Xylocopa) : flowers in the forest give insects food by giving nectar to the bee. While the bee provides for the pollination of the flower to help it reproduce

2. Commensalism: one organism benefits while the other is neither harmed nor hurt
Example: Northern Cardinal & Oak Tree: Birds nest in the tree and  neither harmed nor hurt it in the process

3. Parasitism: one organism preys on another
Example: Tapeworm & American Blackbear: the tapeworm lodges itself in the intestines of the mammal and it feeds on it until the bear eventually dies
