南极磷虾在碳循环中的作用是什么？
What role does Antarctic krill play in the carbon cycle?
磷虾摄食表层藻类等，其排泄与尸体沉降至深海，将碳从表层带往海底（生物泵），并是鲸、企鹅、海豹的关键食物，影响整个南大洋碳与食物链。
Krill graze surface algae; their fecal pellets and carcasses sink, transporting carbon from surface to deep sea (biological pump), and they are key prey for whales, penguins and seals, shaping Southern Ocean carbon and food webs.

商业捕捞磷虾主要用于什么？
What is commercial krill fishing mainly used for?
多制成水产饲料、宠物食品和 Omega-3 补充剂。过度捕捞会动摇南大洋食物链基础，故设有捕捞限额与海洋保护区争议。
Mostly made into aquaculture feed, pet food and Omega-3 supplements. Overfishing undermines the Southern Ocean food base, so catch limits and marine-protected-area debates apply.

南极磷虾是什么动物的“主食”？
What animals eat Antarctic krill as a 'staple'?
鲸鱼、企鹅、海豹和很多鱼都以磷虾为重要食物，它像南大洋食物网的“小齿轮”。
Whales, penguins, seals and many fish rely on krill as key food; it is like a small gear in the Southern Ocean food web.
