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.
One of the most important types of plankton is phytoplankton. Like land-based food chains, marine food chains begin with creatures capable of producing food from nutrients and sunlight. Phytoplankton do not eat in a traditional sense: They produce energy through photosynthesis.
