Which type of relationship involves one organism benefiting and the other being unaffected?

The relationship described where one organism benefits while the other remains unaffected is known as commensalism. In commensalistic relationships, the organism that benefits derives some form of advantage, such as food, shelter, or transportation, without causing any harm or benefitting the other organism involved.

For example, certain species of barnacles adhere to the shells of turtles. The barnacles gain mobility to access nutrient-rich waters while the turtle is unaffected by their presence. This illustrates the core principle of commensalism, highlighting the asymmetrical benefit where one organism thrives without impacting the other.

Understanding this concept is crucial in studying ecological interactions and the roles organisms play within their environments. It offers insights into biodiversity and species interactions, helping veterinary professionals recognize patterns that may affect animal health and behavior.
