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.
Like other plants, phytoplankton are phototrophs, meaning that they use photosynthesis to create their own food. As such, they contribute to sequestration of carbon dioxide into the biosphere, and have their own rate of primary productivity.n these regions, most of the macro nutrients-such as carbon, nitrogen, and phosphorous-are rarely used up by phytoplankton, despite the greater productivity, because some micro nutrients, especially iron, are far more limiting (Croot et al, 2004).
