(b) Phytoplankton → Zooplankton → Fishes → Fungi

(c) Phytoplankton → Fungi → Zooplankton → Fishes

(d) Zooplankton → Phytoplankton → Fishes → Fungi

This question was addressed to me in examination.

This interesting question is from Ecosystem topic in division Ecosystem of Biology – Class 12

Answer 1

The correct option is (b) Phytoplankton → Zooplankton → Fishes → Fungi

For explanation I would say: A food chain found in any aquatic body is known as an aquatic food chain. In this phytoplankton is the producer, zooplankton is the herbivore, fish is the carnivore, and fungi are the decomposers.
