Cecropias are known for the mutualistic relationship they have with which creature?

A Deer
B Snakes
C Ants

Not only are Cecropias very popular with animals like sloths, monkeys, and toucans for their fruit and leaves, many Cecropia species have a symbiotic relationship with Azteca ants. The ants get to live in the Cecropia’s hollow stems and eat glycogen-rich food produced at the base of the leaves, and in return they defend the tree from plant-eating predators.

The correct answer is Ants.
