Explanation:

A symbiotic relationship is defined as the close interrelationship between two or more species. This relationship is important for ecosystems and, many organisms and provides balance to the environment.

There are 3 types of symbiotic relationship:

1) Mutualism: In this relationship both get benefits.

2) Parasitism: In this relationship, one species gains and other species suffer.

3) Commensalism: In this relationship one species benefits, and the other is not affected.
