Barnacles live on whales. whales carry the barnacles around, which the barnacles feed. the whales are unaffected. this is an example of predation mutualism parasitism commensalism

The correct answer for the blank is-

commensalism.

Commensalism is a long term biological interaction between two organisms belonging to different species where one organism gets benefit and the other organism neither gets benefit nor it is harmed.

In this question, Barnacles living on whales get benefit as they get their food while moving around on Whales. In this interaction, the whales are unaffected.

Thus, this is an example of commensalism.

humans are now responsible for causing changes in the environment that hurt animals and plant species. we take up more space on earth for our homes and cities. we pollute habitats. human activity often changes or destroys the habitats that plants and animals need to survive.
