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.
Phytoplankton, also called algae, are producers that photosynthesize, meaning they convert energy from the sun, carbon dioxide, and other nutrients in the water into food for themselves. They contribute up to 50% of the world's oxygen to the atmosphere.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.hytoplankton, also called algae, are producers that photosynthesize, meaning they convert energy from the sun, carbon dioxide, and other nutrients in the water into food for themselves.
