1 Gastritis: Inflammation of the stomach, often causing nausea and/or pain. Gastritis can be caused by alcohol, certain medications, H. pylori infection, or other factors.  Stomach cancer: Gastric cancer is an uncommon form of cancer in the U.S. Adenocarcinoma and lymphoma make up most of the cases of stomach cancer.
Phytoplankton receive energy through photosynthesis. Photosynthesis is the process of making glucose using sunlight. Carbon dioxide, sunlight, and water combine, producing gluâ¦cose sugars that the being can use for energy.  Zooplankton however feed off phytoplankton and decaying matter. They are known as detrivores.
Prokaryotes get energy by performing chemical reactions within the cell. All organisms are able to do glycolysis, which splits a molecule of glucose in half and releases a little bit of energy in the form of #ATP# (adenosine triphosphate). Some prokaryotes are also capable of additional reactions that produce more energy, similar to what happens in the mitochondria of eukaryotes.
