Gastric ulcer is nothing more than an injury to the tissue lining the stomach. It may also be called peptic ulcer or stomach ulcer.
The most common cause of ulcer formation is the proliferation of a bacterium called<em> Helicobacter pylori. </em>There are other less common factors such as diet, overuse of drugs, smoking, stress and alcohol.
The best way to prevent an ulcer contraction is to maintain hygiene habits to prevent <em>Helicobacter pylori</em> infection. It is also good to avoid excessive consumption of alcohol, smoking and medications such as pain killers.
Photosynthesis
Photosynthetic bacteria use the energy of the sun to make their own food. In the presence of sunlight, carbon dioxide and water are turned into glucose and oxygen. The glucose is then turned into usable energy. Glucose is like the "food" for the bacteria. An example of photosynthetic bacteria is cyanobacteria, as seen in the opening image. These bacteria are sometimes called blue-green algae, although they are not algae, due to their numerous chlorophyll molecules.
Decomposers
Bacteria known as decomposers break down wastes and dead organisms into smaller molecules. These bacteria use the organic substrates they break down to get their energy, carbon, and nutrients they need for survival.
Chemotrophs
Bacteria can also be chemotrophs. Chemosynthetic bacteria, or chemotrophs, obtain energy by breaking down chemical compounds in their environment. An example of one of these chemicals broken down by bacteria is nitrogen-containing ammonia. These bacteria are important because they help cycle nitrogen through the environment for other living things to use. Nitrogen cannot be made by living organisms, so it must be continually recycled. Organisms need nitrogen to make organic compounds, such as DNA
