Solution:Concept: The above given statement is true.
The food chain explains the relationship between different organisms. Yes, this statement is absolutely true. The above food chain is of the aquatic ecosystem.
Every food chain starts with producers, then eaten by herbivores later they are eaten by fish and ultimately by larger fishes. Here, Phytoplankton is phototrophs and produce their own food. Zooplankton eat phytoplankton, later eaten by fishes. The food chain is a linear network of links in a food web that starts from producer organisms and ends at an apex predator species, detritivores, or decomposer species. A food chain also shows how the organisms are related to each other through the food they eat.
Hence, option 1 is the correct answer.
