उत्तर

Orchids are epiphytes that inhabit mangos. In this example of commensalism, the mango tree is virtually neither aided nor injured, while the orchid obtains support and access to light and air. In addition to using specialised aerial roots called velamen to absorb moisture from the atmosphere, epiphytic orchids produce their own sustenance through photosynthesis.
