Explanation:

For Mutualism: The description "The relationship between two or more organisms that live closely together and benefit from each other. Example: fungus and algae" matches mutualism, where both species gain. For Commensalism: "A relationship in which one organism benefits and the other organism is neither helped nor harmed. Example: shark and remora fish" fits, as remora benefits, shark is unaffected. For Parasitism: "A symbiotic relationship in which one organism benefits at the expense of another organism. Example: fleas and dogs" is correct, as fleas harm dogs while benefiting.

Answer:

Mutualism: The relationship between two or more organisms that live closely together and benefit from each other. Example: fungus and algae.
