Question

write a importance of microbes in nitrogen fixation

Answer 1

Nitrogen is a component of proteinsand nucleic acids and is essential to life on Earth. Although nitrogen is abundant in the atmosphere, most organisms cannot use it in that form. Nitrogen-fixing bacteria accomplish more than 90 percent of all nitrogen fixationand thus play an important role in the nitrogen cycle. Because of these bacteria, legumes have the nitrogen necessary to make lots of proteins, which, in turn, is why beans are such a good source of dietary protein for humans and other animals. Additionally, legumes and certain cereal grasses are often grown as green manures and for crop rotation on farms as an organic source of nitrogen for other crops.
