Explanation about Commensalism Mutualism, Parasitism, Competition, and Predation are given below.

There are various symbiotic relationship formed between the organisms present in the environment. These relationships are Commensalism Mutualism, Parasitism, Competition, and Predation. In Commensalism relationship, one organisms gets benefits while the other neither get benefit nor harm. In mutualism, both organisms gets benefits from one another.
