Answer:
I think they are beneficial for the life of those symbiotic organisms that require yes or yes from another to be able to live.
Although an ecosystem could not be carried out if only this relationship would occur, since symbiotic relationships we have an organism where it needs another to live and even removes the necessary nutrients for it, that is why the chain should continue with other types of relationships .
Step-by-step explanation:
The symbiosis is defined as "Intimate association of organisms of different species to mutually benefit in their vital development" that is why adequate coexistence between these living organisms is needed, otherwise this phenomenon would not occur.
A very good example of the symbiosis is: Bees and plants where the bee is the pollinating agent of the plant so that it continues to reproduce and the plant is the bee's food source.
Therefore I believe that the development of this type of relationship is VITAL, and very fundamental, otherwise I do not know if an ecosystem or a balanced ecosystem could be carried out.
