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.
