BIOLOGY HELP!!!! symbiotic relationship between trees and orchids??
The relationship between host (tree) and orchid can be called commensalism because the orchid is nourished by the tree without harming it, but this is only if there are not too many orchids growing on the tree. This changes when the epiphytes increase beyond a certain number. For instance, if the orange trees in Central American plantations are not regularly stripped of the epiphytes growing on them, they stop bearing fruit. Later the trees become crippled. If this happened the relationship would be considered parasitiam because the orchid is benifitting while the tree is being harmed.
