A bird has fluke worms in its intestines, and they feed on the bird’s tissues and infect them. What is this an example of?

a.) parasitism

b.) defensive mutualism

c.) commensalism

d.) dispersive mutualism

Parasitism.

In parasitism, one organism benefits from the relationship, but at the expense of another. When the bird has fluke worms in its intestines, the fluke worm is able to feed on the bird’s tissues, which benefits the fluke worm. However, this can infect the bird, causing it harm.

Hope this helps!
