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.
To understand the entire ecosystem ... we need to better understand the plankton. Photosynthesis by the phytoplankton accounts for up to half of global primary production. They also provide the primary food source for the zooplankton, and together form the base of the oceanic food chain.Larger and larger zooplankton, fish, and mammals depend on these plankton for their survival.n the smaller end of the spectrum exist bacteria (bacterioplankton) and viruses (virioplankton). Plankton also consist of the early life stages of much larger organisms, such as fish eggs and larvae (ichthyoplankton), which are both part of and dependant on the plankton itself.
