What is the definition of Symbiotic mode of nutrition?
Your friend Ayushi is right.
Symbiosis is mutually beneficial association existing between two organisms and both organisms derive benefit from each other without causing any harm to each other. Examples: Leguminous plants shows symbiotic nutrition mode. Alga and fungus live together. Fungus provides water and shelter to alga. In return, alga provides food prepared by photosynthesis.
