Answer:
The correct answer is c. c.Squid feed on Zooplankton.
Explanation:
In a marine food chain, phytoplankton are the primary producers which can make their own food by the process of photosynthesis.
Then these primary producers are consumed by primary consumers that are zooplanktons. Then these zooplanktons are consumed by small fishes that means small fishes are secondary consumers.
The tertiary consumers are squids that feed on small fishes, not on zooplanktons. Seals are on top of trophic level because they consume squids. So squids feed on small fishes, not zooplanktons, therefore, the correct answer is c.Squid feed on Zooplankton.
