Symbiosis

What is symbiosis? Give one example.

Answer: Symbiosis -A Special Mode of Nutrition-:

When two organisms live together and share shelter and nutrients, their association is called symbiosis or symbiotic relationship, and the organisms are called symbionts. They mutually help each other.

 Lichen is an example of symbiotic relationship between an alga and a fungus that live together and are mutually beneficial to each other. Alga is an autotroph and fungus is a saprotroph. Fungus provides shelter, water and minerals from the soil to the alga. The alga in return prepares food for the fungus by photosynthesis.
