Phytoplankton, Zooplankton, Small Fish, Mammal
Phytoplanktons are the small photosynthetic organism that can produce their own feed and so are the producers in this food chain. Zooplanktons are small organisms incapable of producing their own food and eat phytoplanktons. Small fishes consume zooplanktons since due to their small size they are unable to eat bigger organisms. Mammals eat small fishes since they are omnivorer.
