Amenasalism can be represented as:
Species A (-) : Species B (0)
Species A (+) : Species B (+)
Species A (-) : Species B (-)
Species A (+) : Species B (0)
Ammensalism: It is an interaction between two organisms of different species in which one species inhibits the growth of other species by secreting certain chemicals.
A(-) is inhibited
B(0) is unaffected.
