question: Which type of relationship is formed when an epiphytic orchid grows on a tree branch in the canopy?

choice: (A) parasitic (B) mutualistic (C) commensal

context: Read the passage. Then answer the question. Epiphytic orchids are flowering plants that can grow in tropical forests. An orchid can grow on tree branches in 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. Figure: epiphytic orchids growing on trees in a tropical forest.
