While all of these roles are important in the symbiotic relationship between fungi and bacteria in lichens, one of the primary roles of bacteria in lichens is to provide nitrogen. Bacteria in lichens fix nitrogen from the air, making it available for the lichen to use as a nutrient. This is important because nitrogen is an essential element for growth and metabolism in organisms.
