Question

1. the blue whale swims throughout the atlantic ocean. barnacles attach themselves to the blue whale to be transported through the water. the whale is unaffected. which of the following relationships should deshaun pick? a. mutualism b. commensalism c. parasitic d. invasive species

Explanation:

• Mutualism: Both species benefit. But here, only barnacles benefit (transport), whale is unaffected. So not mutualism.
• Commensalism: One species benefits, the other is neither helped nor harmed. Barnacles benefit (transport), whale is unaffected. This fits.
• Parasitic: One organism (parasite) benefits at the expense of the other (host). Whale is not harmed, so not parasitic.
• Invasive Species: A non - native species that causes harm. Not relevant to the interaction described.

Answer:

B. Commensalism
