Question 1 Report

Rhizobium supplies nitrogen to leguminous plants by
Answer Details
Rhizobium is a type of bacteria that lives in the root nodules of leguminous plants. It is able to fix atmospheric nitrogen, which means it can convert nitrogen gas from the air into a form of nitrogen that plants can use. This process of nitrogen fixation is very important for leguminous plants because it allows them to obtain nitrogen without having to rely on external sources such as fertilizers. The nitrogen that Rhizobium supplies to the plant is in the form of ammonium ions which the plant can absorb and use to synthesize amino acids, proteins, and other important compounds. So, the correct answer is "fixing atmospheric nitrogen".
