What's the difference between parasitism,mutualism,and commensalism!? :confused:

All three are forms of symbiosis--a relationship between two kinds of organism.

A parasite (think tick, mosquito, or tape worm) benefits from the relationship while the host is damaged. The parasite munches on you or steals your food, but either does not kill you or kills you rather slowly, bit by bit.

A commensal benefits from the interaction, but the host is not hurt. For example, ants living near your compost heap may prey on insects attracted to the compost, but you are not injured by this.

In mutualism, both organisms benefit. The bacteria living in your intestines benefit from the food you eat and most of them also help you digest food, produce vitamin K and other things not yet fully understood. Mice raised with no intestinal bacteria need 30% more food than normal mice with intestinal "flora."

Check out Wikipedia (http://en.wikipedia.org/wiki/Symbiosis) for more information.

Mutualism is when both organisms benefit

Commensalism is when 1 organism benefits and the other is unharmed

Parasitism is when 1 organism benefits when the other is harmed

Equals Big Difference. I know this is probably homework, brizeida, but couldn't help myself.

Why are you acting hysterical? You have posted this question in three places and got several fair answers to your question and yet you act liked nobody has helped you.
