What role do bacteria play in the nitrogen cycle?

Bacteria's role in the nitrogen cycle is that bacteria transforms nitrogen into molecules.

The process of nitrification, nitogen fixation and denitrification in nitrogen cycle is performed by bacteria.

Explanation:

Nitrogen cycle is the process of conversion of nitrogen into different chemical forms as it circulates in the environment. Main steps of nitrogen cycle are nitrogen fixation, assimilation, ammonification, nitrification, denitrification and reduction of nitrate to ammonia.

Azotobacter bacteria fix the atmospheric nitrogen into nitrites and nitrates. Nitrosomonas bacteria convert ammonia into nitrates ( nitrification) and Pseudomonas under anaerobic condition converts the nitrates back into the nitrogen gas.

amber has allowed scientists to study dna that has been preserved over millions of years.

protein makes up the building blocks of organs, muscles, skin, hormones and pretty much everything that matters in your body.

some choices are:

peanut butter

seeds

eggs

yogurt

meats

fish

so pretty much meat, dairy, nuts, and grains.
