Question
An orchid plant is growing on the branch of a mango tree. How do you describe this interaction between the orchid and the mango tree?

Solution
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.
