classify bacteria and nutritional requirement
Answers
Answer:
Classification of Bacteria on the basis of Nutrition
Nutrition is substances used in biosynthesis and energy production and therefore are required for all living things.
Bacteria, like all living cells, require energy and nutrients to build proteins and structural membranes and drive biochemical processes.
Bacteria require sources of carbon, nitrogen, phosphorous, iron and a large number of other molecules.
Carbon, nitrogen, and water are used in the highest quantities.
The nutritional requirements for bacteria can be grouped according to the carbon source and the energy source.
Some types of bacteria must consume pre-formed organic molecules to obtain energy, while other bacteria can generate their own energy from inorganic sources.
Answer:
Bacteria can be classified nutritionally based on their energy requirements and on their ability to synthesise essential metabolites. Bacteria which derive energy from sunlight are called phototrophs. Those that obtain energy from chemical reactions are called chemotrophs.
