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.
Plankton is the mass of microscopic plants and animals that float near the surface of large lakes and oceans. Phytoplankton is the plant matter while zooplankton is the animal component. Zooplankton feeds on phytoplankton and acts as a link in the food chain between plants and larger animals.Without these tiny creatures to graze on the phytoplankton, there would be a catastrophic collapse of the entire marine ecosystem and bioweb.ooplankton feeds on phytoplankton and acts as a link in the food chain between plants and larger animals.
