Monera play crucial roles in various ecological processes, including nutrient cycling, nitrogen fixation, and decomposition. Some species of bacteria are used in industrial processes, such as fermentation and bioremediation. Additionally, certain bacteria are used in the production of antibiotics and other pharmaceuticals.
Monera are found in virtually every environment on Earth, from deep-sea hydrothermal vents to the human gut. They play a vital role in maintaining the balance of ecosystems and are essential for the survival of many other organisms.
