The nitrogen fixation bacteria makes the nitrogen available for the plants directly into the soil. This is an example of mutualism, where both bacteria and organisms are benefited.
- Most leguminous plants like peas, bans, and cloves have colonies of nitrogen fixation bacteria.
- These bacteria are found attached to the roots nodules and tend to fix the nitrogen. Through this, the bacteria gain sugar from the plant.
Hence mutualism is the end product of the interaction. This option A is correct.
