In nitrogen fixation, the plant obtains the nitrogen it needs to synthesize proteins, while the bacteria obtain carbon from the plant and a secure environment to inhabit within the plant roots. Which statement best explains the symbiotic relationship between the plants and the bacteria? A) Both the plants and the bacteria benefit from the process of nitrogen fixation, showing commensalism. B) The plants benefit and the bacteria are unaffected by the process of nitrogen fixation, showing commensalism. C) Both the plants and the bacteria benefit from the process of nitrogen fixation, making it a mutualistic relationship. D) The bacteria benefit and the plants are unaffected by the process of nitrogen fixation making it a mutualistic relationship.

Symbiotic relationship is a relationship between two organisms in which both organism benefit each other or both are equally depended on each other.
In nitrogen fixation, both the plants and the bacteria benefit from the process of nitrogen fixation,making it a mutualistic relationship or symbiotic relationship between the plants and the bacteria.

in nitrogen fixation plants provide carbon and shelter to the bacteria and in return bacteria provide nitrogen to the plants which helps plants to synthesize proteins and this association shows the symbiotic or mutual association or relationship.
