Beneficial: Mutualism= Both benefit Commensalism= Only one benefits & other is not harmed or helped Harmful: Parasitism= One benefits & Host slowly harmed Organism Interrelationships:Symbiosis=a close long term relationship between two or more species
+ = benefits, - = harmed, 0 = neutral (neither harmed nor helped)
Fungi carbon dioxide moisture Algae food Oxygen Mutualism (Both Benefit) Lichen=Fungus + algae
Commensalism(One Benefits) Whale & Barnacles Whale • unharmed Barnacles • Protection from predators • Transportation to new food sources
Commensalism (One Benefits) Clown Fish & Sea Anemonae* Clown fish dwell among the tentacles of tropical sea anemones. The anemomes are capable of stinging most fishes, but the clown fish possess a special mucous coating that somehow prevents the discharge of the anemone's stinging cells. The fish is protected from predators by the stinging cells. *This relationship is often shown as mutualism as well, so read the scenario. If mutualism, it will typically discuss how the territorial nature of the fish wards off predators of the anenome and helps clean the anenome.
