Question

read the passage. then answer the question. julia butterflies get most of their nutrients by eating nectar from flowers. but a julia butterfly cannot get enough salt from nectar to survive. the butterfly finds some of the salt it needs in the tears of a reptile called a spectacled caiman. to get the salt, the butterfly lands on a caimans head and uses its straw - like mouthparts to drink tears directly from the caimans eye! the caiman is not helped or harmed by the butterfly. while the butterfly drinks, the caiman often does not move or even blink. which type of relationship is formed when a julia butterfly drinks a spectacled caimans tears? commensal mutualistic parasitic

Explanation:

In commensalism, one organism benefits while the other is neither helped nor harmed. The Julia butterfly benefits by getting salt from the caiman's tears, and the caiman is not affected. In mutualistic relationships, both organisms benefit. In parasitic relationships, one organism (parasite) benefits at the expense of the other (host). Here, only the butterfly benefits and the caiman is neutral, so it's commensal.

Answer:

commensal
