Answer:
Symbiosis can be described as a biological interaction between organisms of different species.
There are different forms of symbiosis. A type of symbiosis in which both the organisms benefit from each other is called as mutualistic symbiosis.
The blue fungus and the pink plant are able to grow more in size when placed side by side because they undergo symbiosis. They both help each other and develop a symbiotic relationship which allows both of them to have enhanced growth.
