food and warmth and moisture
Bacteria need a suitable temperature range to survive, as extreme temperatures can denature their proteins. They also need a source of nutrients to provide energy for growth and metabolism.
Bacteria do not need a host organism to live and multiply.
I believe not because they are living things and need oxygen instead or they only need something to live in to reproduce and live.
It depends on the bacteria. Cyanobacteria are a good example of a bacteria that can. There are obligate anaerobes, obligate aerobes, and organisms that can live with or without it.
Bacteria CAN live on Earth.
Bacteria that must have oxygen to survive are called obligate aerobes. Some bacteria can live with or without oxygen and are called facultative anaerobes.Anaerobes = No oxygenAerobes = Oxygen
There shape, if they need oxygen, and where they live.
It depends on the bacteria. Some need a lot of oxygen, some only a little and in some oxygen will kill them. While most bacteria live in a narrow range of pH, some will be able to live in higher or lower ranges.
Advantages: Theres a bacteria that you actually need to help you live Disadvantage: Theres others that can hurt you
These bacteria help in digestion and in destroying harmful organisms. Intestinal bacteria also produce some vitamins needed by the body.
Anaerobic bacteria do not require oxygen to live. They are able to generate energy from sources other than oxygen, such as fermentation or anaerobic respiration. Some examples of anaerobic bacteria include Clostridium and Bacteroides.
Well it would be good and it would have downfalls. for me i believe it would be ok but with out diseases you can't heal. Your blood cells and drugs are simple made out of bacteria. so it would be hard to live. then theres bacteria that you need in order to live.
