Bacteria play crucial roles in various ecosystems and human activities. They are essential for nutrient cycling, such as nitrogen fixation, which enriches soil for plant growth. In biotechnology, bacteria are used for bioremediation to detoxify polluted environments and in the production of antibiotics, enzymes, and fermented foods. Additionally, they aid in digestion and maintain gut health in humans and animals.
