-Capuchin Monkeys and Flowering Trees. When the Capuchin Monkey feeds on nectar in the Flowering Tree, it gets pollen on its face, which eventually transfers to other flowers. The Flowering Trees provide the Capuchin Monkey with food, while the Capuchin Monkey pollinates the flowers of this tree.
-Ecitoninae (army ants) and Antibirds (a small bird from South America). Ecitoninae are famous for their tendency to take on anything that comes in their way. The antibirds follow this swarm of ants and feed on whatever is left behind after the ants are done with their meal. The ants ruffle insects on the floor and are eaten by the antibirds. The antbirds benefit from the army ants, but the army ants are not benefited nor harmed by the antbirds.
-Phorid Fly (the parasite) and Leaf-cutter Ants (the host). When the Leaf-cutter Ants are collecting leaves, the Phorid Flies attack them and lay their eggs in the crevices of the ant's head. When the eggs hatch, the larvae dig into the ant's body and feed on it, killing the ant. The Phorid Fly gets benefited from the Leaf-cutter Ants, but the Leaf-cutter Ants are harmed.
>Predator and Prey
-Red Poison Dart Frogs and Mosquitos. When the Mosquitos are flying around to find an animal to suck blood from, the Red Poison Dart Frog is trying to find a meal. The frogs reach and grab the mosquitos with their long tongues. Since the Red Poison Dart Frog eats the Mosquito, it is the predator. The Mosquito is the prey because the Red Poison Dart Frog eats it.
