More simple Biology Notes

Relationships
Mutualism	+ +	Two organisms help each other and they both benefit (good for both)
Predation	+ -	(Predator/Prey) Predator kills the prey. + predator eats, - prey dies
Commensalism	+ /	Good for one animal. Not good or bad for one animal
Parasitism	+ -	Good for the parasite (gets food) and bad for the host (it hurts)

1.     Mutualism ++

Two organisms live and work together (they help each other) it is good for both.

Example: Bee/Flower Relationship

Bee (+) because of nutrition

Flower (+) because makes new flowers (spreads pollen)

2.     Predation + -

Predator/Prey: It is good for the predator because they get nutrition (food) but is bad for the prey because they die and get eaten.

Example: Eagle/Mouse

Eagle (predator) (+) Good because gets protection

            Mouse (prey) (-) because gets nutrition

3.     Commensalism +/

The host is not helped or hurt and the other animal benefits (is helped) because

Example: Clown Fish/Anemone

Clown Fish (+) because gets protection from the anemone

            Anemone (/) not helped or hurt

4.     Parasitism +-

One organism needs a host to live. Good for the parasite and bad for the host. The parasite takes nutrients from the host.

Example: Tick/Dog

            Tick (+) because it gets nutrition (blood) from the host

            Dog (-) it hurts the dog (host)
