Question

epiphytic orchids growing on trees in a tropical forest the canopy, or upper layer of the forest. in the canopy, the orchid gets more sunlight than it would in the shadowy lower parts of the forest. the additional sunlight allows the orchid to perform more photosynthesis. there is also more wind in the canopy, which helps the orchid spread its seeds to other branches. the orchid does not damage the tree it grows on, but it also does not provide resources to the tree. which type of relationship is formed when an epiphytic orchid grows on a tree branch in the canopy? commensal mutualistic parasitic

Explanation:

In a commensal relationship, one organism benefits while the other is neither helped nor harmed. The epiphytic orchid benefits from more sunlight and wind - assisted seed - spreading by growing on the tree, and the tree is not damaged or benefited. In mutualistic relationships, both organisms benefit. In parasitic relationships, one organism benefits at the expense of the other.

Answer:

commensal
