Question

this food web is from an ocean ecosystem in the ross sea, off the coast of antarctica. which arrows show energy moving from a secondary consumer to a decomposer? select all that apply. the arrow between the adélie penguin and the polychaete worm the arrow between the krill and the icefish the arrow between the silverfish and the adélie penguin

Explanation:

First, identify secondary consumers (eat primary - consumers) and decomposers (break down dead organisms). In this food - web, polychaete worms are decomposers. Adélie penguins are secondary consumers. The arrow from Adélie penguin to polychaete worm shows energy transfer from a secondary consumer to a decomposer. Krill are primary consumers, icefish are secondary consumers, so the arrow from krill to icefish is not from a secondary consumer to a decomposer. Silverfish are primary consumers, Adélie penguins are secondary consumers, so the arrow from silverfish to Adélie penguin is not from a secondary consumer to a decomposer.

Answer:

the arrow between the Adélie penguin and the polychaete worm
