Explanation:

Step1: Identify primary and secondary consumers

Primary consumers eat producers, secondary consumers eat primary - consumers. In the food - web, krill, microzooplankton, and copepod are primary consumers. Emperor penguin and icefish are secondary consumers.

Step2: Analyze each option

• For the arrow between krill and emperor penguin: Krill is a primary consumer and emperor penguin is a secondary consumer, so this arrow shows matter moving from a primary consumer to a secondary consumer.
• For the arrow between microzooplankton and krill: Microzooplankton and krill are both primary consumers, so this arrow does not show matter moving from a primary consumer to a secondary consumer.
• For the arrow between copepod and icefish: Copepod is a primary consumer and icefish is a secondary consumer, so this arrow shows matter moving from a primary consumer to a secondary consumer.

Answer:

the arrow between the krill and the emperor penguin, the arrow between the copepod and the icefish
