Commensalism is

• one species benefits, the other is not affected
• both species benefit
• both species are harmed
• one species benefit, the other is harmed

an example of producer consumer relationship would be

• lion eating a deer
• grasshopper getting energy from grass
• hawk getting energy from snakes
• earthworm breaking down dead material
