Bacterioplankton are bacteria and archaea, which play an important role in remineralising organic material down the water column (note that many phytoplankton are also bacterioplankton). Plankton are found throughout the oceans, seas and lakes of Earth.
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.
