food and warmth and moisture
Bacteria do not need a host organism to live and multiply.
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.
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.
There shape, if they need oxygen, and where they live.
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
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.
Bacteria live any place you can think of. (Everywhere.)
