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 /ËfaÉªtoÊËplaeÅktÉn/ ËfaÉªtoÊËplÃ¦ÅktÉn are the autotrophic components of the plankton community and a key factor of, oceans seas and freshwater basin. Ecosystems the name comes from The greek words (ÏÏÏÏÎ½), phyton  meaning , plant and (ÏÎ»Î±Î³ÎºÏÏÏ), planktos meaning wanderer or. drifterhytoplankton obtain energy through the process of photosynthesis and must therefore live in the well-lit surface layer (termed the euphotic zone) of an ocean, sea, lake, or other body of water.
