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.
There are many types of phytoplankton, but two main are most common: 1) diatoms and 2) dinoflagellates. Diatoms are single-celled algae that have chloroplasts and can undergo photosynthesis.Dinoflagellates are also single-celled and have two whip-like tails called âflagella.â Although many dinoflagellates also have chloroplasts, not all do.oth types of phytoplankton can be autotrophic and use photosynthesis to harvest the sunlight to produce their own energy, but some dinoflagellates are heterotrophic and rely on eating other organisms for energy; as far as we know, there are no heterotrophic diatoms.
