17. Some birds live in close association with horses. These birds feed on
insects that are parasites to horses. Which type of relationship between
the horses and these birds does this illustrate?
Commensalism
Mutualism
Parasitism
Predation
I would say Mutualism because the birds help protect the horses from the parasites but the birds get food from the parasites thus making them each get something out of the relationship.
