Bacteria are the organisms that captures atmospheric nitrogen for the process of nitrogen fixation.
Bacteria are usually found in the root nodes of plants and soils. They establish a symbiotic relationship with plants where they fix nitrogen essential for the plant in turn gain some advantage like nutrition and protection from the plant.
Bacterial like azotobacter are very important in the nitrogen cycle.
The help to draw up nitrogen from the atmosphere for use by plants.
When bacteria decompose, they leave behind nutrients. These nutrient then filter unto the roots of the plants via the water that it sucks up. A loss in certain nutrients could be the death of this plant.
