Interrelationships

Working together to remove the bad guy

Symbiosis• A close relationship between

two different species

Three kinds of symbiosis1.Mutualism2.Commensalism3.Parasitism

In each of these relationship organisms may provide different benefits.

1. food2. protection 3. cleaning4. transportation5. combination of above

Mutualism

• A close relationship where both organisms benefit

Sharing each others food

Mutualism• The clownfish is protected

from predators by living in the sea anemone. It develops immunity by touching a few tentacles over time and creates a mucus covering and thereby is protected from that particular sea anemone’s stinging cells.

• The sea anemone gets food

by having the clownfish attract predators. The clownfish also removes parasites and keeps water circulating near the sea anemone.
