Question

Why do clownfish and sea anemone pair up? What is the relationship called?

Answer 1

Hint: Population interaction is a process in which different organisms interact with each other for their benefit or any other use. such as even a plant species which makes its own food cannot survive alone; it needs soil microbes to break down the organic matter in the soil.

Complete answer: Commensalism is the interaction in which one species benefits in the other species is neither harmed nor benefited.
An orchid growing as an epiphyte on a mango branch and barnacles growing on the back of a whale benefit while neither the mango tree nor the whale derives any apparent benefit.
Another example of commensalism is the interaction between sea anemone that has stinging tentacles and the Clownfish that lives among them.
The fish gets protection from predators which stay away from the stinging tentacles while the sea anemone does not appear to derive any benefit by hosting the clownfish.

Additional information:
1. Types of population interaction. There are commonly 6 types of population interaction.
2. Mutualism is a population interaction in which both the organisms are benefited.
3. competition is a population interaction in which both the organisms are harmed.
4. Predation and parasitism type of population interaction in which one organism is harmed and another is benefited.
5. Commensalism is a type of population interaction in which one organism is benefited and another is neutral.
6. In Amensalism one organism is harmed and another remains unaffected.

Note: All organisms on earth are linked by one another through interaction among them, some are beneficial and some are harmful but all are necessary.
