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.
Mitochondria and Energy. Mitochondria, an organelle found in both plant and animal cells, contains protein-rich components called cristae, which produce ATP. ATP is converted to adenosine diphosphate (ADP), a process which releases energy.denosine triphosphate (ATP) is a high-energy molecule contained in the nucleus of eukaryotic cells. This molecule provides all energy needed for various physiological processes, and is renewed through oxidation, so a cell always contains a supply of ATP to fuel the energy demands of the organism.
