What is symbiosis? Symbiosis is the cause and effect of two organisms living together.

TYPES of SYMBIOSIS Mutualism Parasitism Commensalism both organisms benefit one organism benefits one organism is unaffected one organism is harmed

Parasitism: one benefits, one is harmed Example 1: Acacia plant with ant galls Ants lay eggs on acacia tree Acacia covers the infected area with brown flesh (gall)

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

Commensalism: one benefits, one is unaffected Example 3: Cattle with cattle egrets Cattle 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 unaffected

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

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

Assignment On the next clean page in your IAN, Write the 3 types of Symbiosis, leaving 5 lines beneath each one. For the remainder of class, write down 5 examples of EACH TYPE of symbiosis underneath the type name. Must be relationships of organisms you have seen in your life. EXAMPLE: Parasitism Fleas on dogs
