Example 1: Acacia plant with ants

Mutualism: both benefit
Example 2: Moray Eel with Cleaner Fish
Moray Eel gets a clean mouth Cleaner Fish gets a meal

Commensalism: one benefits, one is unaffected
Example 3: Cattle with cattle
egretsCattle stir up insects
as they eat grass
Egrets hang
around and eat insects

Commensalism: one benefits, one is unaffected
Example 4: Clown fish with anemone
Clown fish gets
protection Anemone is
probably unaffected

Mutualism: both benefit
Example 5: Antelope with Oxbird
Antelope gets rid of it’s
parasites Oxbird gets a meal

Parasitism: one benefits, one is harmed
Example 6: Taenia worm in human eye
Worm infects human blood
streamHuman may go
blind
