Symbiosis: Mutualism, Commensalism, Parasitism

Jump to Comments

Symbiosis basically means ‘living together’ . These symbiotic interrelationships can be divided into three main categories; Mutualism, when both species involved benefit from the relationship, Commensalism, when one species benefits and the other isn’t affected, and Parasitism, when one species benefits, and the other is harmed in the process.

Commensalism: One partner living on the other with no obvious effect on the second.
Parasitism: One partner living on the other with detrimental effect on the second.
Mutualism (symbiosis in a strict sense): Advantages for both partners.

CAN YOU GUESS IS IT..

MUTUALISM, PARASITISM, OR COMMENSALISM??
