Answer:
Although these two may seem somewhat similar, in the broad view, they are two highly different terms.
Mutualism is the equally-beneficial state of the relationship between two organisms. This involves both of the organisms getting their needs sufficed and maintaining a healthy relationship.
Ex. Bee receiving nectar - Flower getting pollinated.
(Hint: Mutualism - Mutually/equally good for both.)
Parasitism is the solo-beneficial state of the relationship between two organisms. This involves only one of the organisms getting their needs sufficed, thus hurting the other organism in the process.
Ex. A flea gets food, shelter, and protection. - Dog feeling itchy, getting blood drawn from themself, and weakening their immune system to foreign substances.
(Hint: Parasitism - One organism acts like a "parasite" to another.)
