Which of the following BEST describes the relationship between these two species as presented above?


Both species benefit from the others' presence in the environment.


The egrets benefit from the cattle, but the cattle are harmed by the egrets.


The egrets benefit from the cattle, and the cattle are unaffected by the egrets.
