2.  Mutualism is when both organisms benefit from the relationship.  Ex: A rhino is not irritated because birds are eating fleas/bugs off of him and the birds get a free meal and a free transport ride.

3.  Parasitism occurs when one organism benefits from the relationship while the other organism is harmed.  Ex: Fleas on a dog

4.  Commensalism happens when one organism benefits from the relationship and the other organism is not harmed.  Ex: Fish have a home in reefs and the reefs are not harmed.

5.  Scavenger is an organism that eats other dead organisms.  Ex: Vulture scavenging for dead food.

6.  Predator is when its hunting a prey.  Prey is when its hiding from the predator.  Ex: Lion is hunting the giraffe.

7.  Camouflage occurs when a predator is hiding to snatch up prey or when a prey is hiding from a predator.  Ex: A moth blending in with a tree.

8.  Decomposer occurs when an organism decomposes another organism.  Ex: Fungi eat dead matter.

9.  Competition happens when two organisms fight over the same resources.  Ex: Lion and cheetah fighting for food, ants fighting for a crumb, &
