Transcript of 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• 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.
