• One species benefits, the other is harmed

• One species benefits, the other is unaffected

• Both species are harmed

In amensalism, what happens to the species involved?

• One species is inhibited or killed, while the other is unaffected

• Both species benefit

• Both species are harmed

• One species benefits, the other is harmed
