Which of the following scenarios is representative of commensalism?
a.
tapeworms living in a mammal’s intestinal tract
b.
bees pollinating flowers
c.
birds following grazing animals who stir up insects
d.
clown fish living among sea anemones

C : Birds following grazing animals who stir up insects

Explanation: Commensalism is a social interaction between two species in which one benefits and the other is not negatively or positively affected by this. In this case, the grazing animal stirs up the insects exposing them to the birds who feed on them. However, the grazing animal does not benefit or lose anything from this interaction.
