Which of the following best describes the difference between a mutualistic relationship and a parasitic relationship?

The main difference between the mutualistic relationship and parasitic relationship is that in case of mutualism both of the organism are benefited by the process but in case of parasitism one is harmed and other one is benefited.

Both the process of mutualism and parasitism shows the biological interaction between the organisms.

In case of parasitism the organism causing disease survives in the body of the host cell and causes harm to the host cell and gets benefit from host cell.

Incase of mutualism both the organism are equally benefit by helping each other to survive in a better way.
