Symbiotic Relationships symbiosis - the relationship between two different individual species that live together in a close relationship (living together) The word symbiosis can be broken down into two parts to determine its meaning sym means together bio means life

Types of Symbiosis There are three types of symbiotic relationships Mutualism Commensalism Parasitism

Mutualism mutualism - a relationship where both organisms benefit The acacia galls are homes to stinging ants and the ants defend acacia from other insects that would harm tree leaves.

Mutualism Flowers and their Pollinators (Example:  Bees and hummingbirds gather nectar and spread pollen.)

The moray eel gets a clean mouth and the cleaner fish gets a meal. Mutualism The moray eel gets a clean mouth and the cleaner fish gets a meal.

Mutualism Algae and Fungi (Lichen) - Alga gets water and nutrients from the fungus and the fungus gets food from the algae.

Mutualism Many herbivores such as cows, sheep, deer, horses and rabbits depend on bacteria that live in their stomachs to break down the plant material.

Mutualism The corals get food and the algae are protected.

Commensalism One species uses a second organism for housing such as small mammals or birds that lives in holes in trees or orchids which live in trees. Orchid in rainforest Venezuela

Commensalism Cattle stir up insects as they eat grass and the egrets hang around and eat insects.

Commensalism Clown fish get their protection from the sea anemone and the anemone is unaffected.

Parasitic isopod on fish Parasitism parasitism – a relationship where one organism benefits (parasite) while the species it depends on (host) is harmed host – an organism on which a parasite lives Parasitic isopod on fish

Parasitism Ticks and fleas that live in a host animal's fur bite the animal and drink its blood are parasites.

Parasitism Mistletoe takes moisture and nutrients from the plant while the woody plant has to support itself and the mistletoe.

Parasitism Insects such as mosquitoes feeding on a host are parasites.

The tick eats the blood of a human and the human receives Lyme disease from the tick. Parasitism
