what type of symbiotic relationship is a bird building a nest in a tree? mutualism parasitism commensalism
Answer
Brief Explanations:
In commensalism, one organism benefits while the other is neither helped nor harmed. When a bird builds a nest in a tree, the bird benefits from the shelter and support the tree provides, but the tree is generally unaffected by the presence of the nest. In mutualism, both organisms benefit; in parasitism, one organism (the parasite) benefits at the expense of the other (the host).
Answer:
Commensalism
