a student has to give a presentation on mutualism. in doing research for his presentation, he takes notes on the relationships shown.
click on the relationship that the student should use in his presentation as an example of mutualism.
barnacles on a whale
barnacles are moved through nutrient - rich waters.
birds on a rhinoceros
birds eat parasites off rhinoceros.
fleas on a wolf
fleas feed on the wolf’s blood and spread disease.

Explanation:

To determine mutualism, we analyze each relationship:

• Barnacles on a Whale: Barnacles benefit (get moved to nutrient - rich waters), but it's not clear if the whale benefits. This is likely commensalism.
• Birds on a Rhinoceros: Birds eat parasites (benefit), and the rhinoceros gets rid of parasites (benefit). This is mutualism as both species benefit.
• Fleas on a Wolf: Fleas benefit (feed on blood), but the wolf is harmed (gets diseases). This is parasitism.

Answer:

Birds on a Rhinoceros (the relationship where birds eat parasites off rhinoceros)
