Question
Write an aquatic food chain.
Solution
An aquatic food chain is one that operates in a water body such as a pond, a lake, or an ocean.
Phytoplankton → Zooplankton → Small Fish → Larger Fish → Sharks
In this aquatic food chain, energy flows from the producers (phytoplankton) up through various consumer levels to the apex predators (sharks). Each level plays a role in ecosystem stability, nutrient cycling, and energy transfer.
