The interaction you are describing is called commensalism.

Explanation:

• Commensalism is a type of symbiotic relationship between two organisms.
• In this interaction, one organism benefits (is helped).
• The other organism is neither helped nor harmed.

Example:

• Barnacles attaching to a whale: Barnacles get transportation and access to food particles, while the whale is unaffected.

If you want, I can provide more examples or details about different types of symbiotic relationships!
