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 are organisms that float on or near the surface of the water. Most are rounded and single-celled. All phytoplankton use photosynthesis for their energy, but some get additional energy by consuming other organisims. The most common phytoplankton are diatoms and dinoflagellates.
