What are the different kinds of symbiosis?

ParasitismMutualism Commensalism

both organisms benefit

one organism benefits

one organism benefitsone

one organism is

harmed

Page 4: Symbiosis ss

Mutualism: both benefit

Example 1: Acacia plant and Ants

Ants eat the sweet

secretion from the plant.

Ants swarm and attack any

animal that tries to eat the

plant

Page 5: Symbiosis ss

Mutualism: both benefit

Example 2:

Moray Eel with Cleaner Fish

Moray Eel gets a clean mouth

Cleaner Fish gets a meal

Page 6: Symbiosis ss

Commensalism: one benefits, one is unaffected

Example 3: Cattle with cattle egrets

Cattle stir up insects as they eat

Mutualism: both benefit

Example 4: Clown fish with anemone

protection, and a lure to attract

fish

Parasitism: one benefits, one is harmed
