this food web is from an ocean ecosystem in the ross sea, off the coast of antarctica. which arrows show matter moving from a tertiary 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 emperor penguin the arrow between the salps and the icefish

Answer

Explanation:

Step1: Identify tertiary consumers

Tertiary consumers are at the high - end of the food web and eat secondary consumers. In this food web, Adelie penguin is a possible tertiary consumer.

Step2: Identify decomposers

Decomposers break down dead organisms. Polychaete worm can act as a decomposer here.

Step3: Check arrows

We look for arrows from tertiary consumers to decomposers. The arrow between Adelie penguin (tertiary consumer) and polychaete worm (decomposer) shows matter moving from a tertiary consumer to a decomposer. The other two options (krill - emperor penguin and salps - icefish) do not involve a tertiary - consumer to decomposer relationship.

Answer:

the arrow between the Adelie penguin and the polychaete worm
