Algae are producers. This means they produce their own energy, usually through photosynthesis. Like most producers, algae turn sunlight, carbon dioxide and water into glucose for energy.
Some examples of phytoplankton are diatoms and dinoflagellates, which are responsible for seasonal algae blooms. Zooplankton are consumers that eat other plankton. Examples include copepods, krill, daphnia and jelleyfish. They are an important link between primary producers and higher trophic levels.
