Question

Give an example of aquatic food chain.

Answer 1

Food chain existing in the aquatic ecosystem often starts with algae or phytoplankton as producers, then zooplankton, which feed on them. Zooplankton are then eaten by small fish and crustaceans, which in turn get consumed by large fish, sharks and whales.

Phytoplankton→Zooplankton→small fish →large fish
