As the ants march along the forest floor hunting insects and small vertebrates, birds follow and pick off any insects or small vertebrates that fly or jump out of the way of the ants. This situation is an example of what kind of species interaction between the birds and the ants?

B. parasitism
C. mutualism
D. cooperation
E. consumption

Answer 1

Answer: commensalism

Explanation: commensalism is a type of association between organisms.in this association,one organism benefits and derives nutrition from the other.the other organism is neither harmed nor gains anything.

this is compared to parasitism where one organism benefits and the other is harmed.it is compared to mutualism,where both organisms involves benefits.
