An orchid plant is growing on the branch of mango tree. How do you describe this interaction between the orchid and the mango tree?
Orchids are epiphytes. These are the autotrophic plants that lack mechanical tissues and grow on the surface of some other supporting plants. Orchid growing on mango tree derive support from the tree but do not derive nutrition from it. It represents commensalism wherein orchid plant is getting support from its association with mango tree while the later is not affected.
