Symbiosis A relationship where two organisms (of different species) live together.

There are 3 symbiotic relationships: Mutualism: –A relationship where both species benefit. Commensalism: –A relationship where one organism benefits and the other does not benefit and is not harmed. Parasitism: –A relationship where one species harms the other species.

Examples of Mutualism: Termites and Bacteria in intestines –Bacteria live in intestines –Break down cellulose –Bacteria digest wood.

Examples of Mutualism: Rhino and Tick Bird –Tick bird eats ticks off of rhino—YUMMY! DINNER! –Tick bird warns of danger by making noise. –Tick bird eats ticks which can be parasites to the rhino

Examples of Mutualism: Bees and Flowers –Bees use the pollen and nectar to make honey –Flowers need the bees to help the plant reproduce. –They both benefit!

Examples of Commensalism: Clownfish and Sea Anemones –Clownfish live in anemones; this gives them protection –Clownfish have a protective coating on scales that prevent them from getting stung. –Sea anemones do not benefit.

Examples of Parasitism: Tapeworm in Human –Tapeworms live in the intestines of humans and consume materials the host (the human) need! –Tapeworm thrives, the human is harmed.

Examples of Parasitism: Tick on Dog –Ticks attach themselves on to the skin of a dog. The ticks suck the blood of the dog and can transfer diseases. –Tick thrives, the dog is harmed.
