A relationship in which one organism benefits without affecting the other is called commensalism. In this type of symbiosis, one organism benefits by using the resources of the other organism without causing harm or receiving any benefit in return. An example of this is the relationship between barnacles and whales, where barnacles attach to the whales’ skin for transportation and food without harming the whales.
Commensalism is a type of symbiotic relationship where one organism benefits while the other is neither helped nor harmed. In the case of barnacles on a crab, the barnacles attach themselves to the crab's shell, gaining access to water flow and food particles as the crab moves through its environment. The crab is largely unaffected by the presence of the barnacles, making this relationship an example of commensalism.
This type of symbiotic relationship is known as commensalism. In commensalism, one organism derives benefits such as food, shelter, or transportation, while the other organism remains unaffected by the interaction. An example of commensalism is barnacles attaching to the shell of a turtle; the barnacles gain a place to live and access to food while the turtle remains indifferent to their presence.
