Answer:
bacteria decompose rotting plant and animal material
Bacteria are important for a number of reasons. They perform functions that make them important to other life forms plus they are important economically in a number of industries.
Some species of bacteria cause disease and infections, but far more commonly, bacteria are beneficial. They are so important in our own bodies that if all of the bacteria from inside our bodies were removed, we would die without their help.
Bacteria that live inside the stomachs and intestines of animals help with digestion. Bacteria have enzymes that are able to digest tough foods, such as plant fibers, that animals are unable to digest.
Bacteria also play a role in important ecological processes. They are one of the main players in the decomposition of dead plants and help to recycle nutrients back into ecosystems. They are also able to take gases from the atmosphere and turn them into usable nutrients such as carbohydrates and nitrates.
Certain industrial processes utilize the metabolism of bacteria. Bacteria are responsible for the fermentation that leads to the production of foods such as cheese and yogurt. Bacteria are also used in waste treatment facilities to help speed up the process of breaking down human waste, food waste and cleaning products.
Well it helps that they decompose rotting plant and animal material.
