What is this called?

• Food Web

• Food Chain

• Abiotic Factors

Barnacles are animals that cannot move. In order to get food, they attach to whales and catch any floating plankton in the water. The whale is neither helped nor harmed in the interaction. What type of symbiosis is this?

• Mutualism

• Commensalism

• Parasitism

• Neutralism
