Question 1 Report

Which of the following represents the correct order in a possible food chain?
Answer Details
A food chain is a linear sequence of organisms that shows how energy is transferred from one organism to another as they consume each other. The correct order in a possible food chain is Diatom -> Crustacean -> Fish -> Man. Diatoms are microscopic algae that form the base of the food chain. Crustaceans such as zooplankton feed on diatoms, then fish feed on crustaceans, and finally, man feeds on fish. Therefore, the energy and nutrients flow from the primary producer, diatoms, to the top consumer, man, through the intermediate consumers, crustaceans and fish.
