Parasitim+and+mutualism+and+commensalism

a symbiotic relationship in which one species benefits and the other is harmed.
 * Parasitism: **

**Example:** Ticks, tapeworms, tree fungus, diseases.





**Mutualism ** It is a relationship when both species benefits.

**examples: ** **An example of mutualism is a clownfish and sea anemones. They benefit each other because the fish gets a protected home territory and the anemone gets cleaning and also atrracts other fish soo it can eat it. ** **This helps the ecology because each animal benefits one another. ** **so this will not harm the ecosystem. ** **Commensalism ** **It is a relationship when one species benefits and the other is unaffected. ** **Example:**  **an example is when a bird lives in a tree, because a bird has protection from the tree but the tree gets nothing but still does not get harmed. ** **Commensalism follows with ecology because ** **whenever one animal benefits the other is harmless. ** media type="youtube" key="NRqEYroujqA" height="315" width="560" align="center"
