Question

Quizplus · Accepted Answer

Intraspecific competition refers to competition between members of the same species. Male red-winged blackbirds defending nesting sites from other males is an example of intraspecific competition as the males are competing with each other for limited nesting resources within their own species. Option A is an example of mutualism as the butterfly and the daffodil both benefit from their interaction. Option B is an example of commensalism as the tick and flea benefit from their interaction on the dog's back, but the dog is not affected. Option D is an example of predator-prey relationship.
