Question

Rhizobium is an example of? ​

Answer 1

Symbotic relationship

Answer 2

Answer:

Symbiotic nitrogen-fixing soil bacteria that fix atmospheric nitrogen.

Explanation:

• Rhizobium is a gram-negative rod-shaped soil bacterium that fixes atmospheric nitrogen.

• It is found mostly in the root nodules of leguminous plants where it forms a symbiotic association with the plant.

• This bacterium produces an enzyme called nitrogenase which is responsible for reducing nitrogen into ammonia.

• Nitrogen fixation by rhizobium is a crucial biological process. Which can not be done independently which is why it requires a plant host.

• This is often used as a biofertilizer as it serves as a source of nitrogen for nitrogen deficit agricultural soils including those in arid areas.

• Rhizobium is an effective and widely used biofertilizer as nitrogen fixation increases soil fertility and productivity.
