Answer:
A. Puffins receive energy from herring, herring receive energy from krill, and krill receive energy from phytoplankton.
Explanation:
A food chain represents the unidirectional network or path of the flow of energy and the matter in an ecosystem.
The aquatic food chain begins from the small or microscopic organisms called phytoplankton which is autotrophic therefore are considered the producers.
The phytoplanktons are eaten by a variety of other organisms in which the krills which live in the deep sea feeds on these phytoplanktons. The krills are the primary consumers who are eaten by small fish like herring which acts as secondary consumers. These herring are then eaten by the bird-like puffins and large fish which acts as tertiary consumers.
