它一方面大量摄食浮游细菌和微小浮游植物，另一方面被一些经济动物摄食，因此在海洋食物链的传递和生态系统的物质循环中占有重要位置。

浮游植物是河口生态系统中重要的初级生产者，是海洋食物链的基础环节，影响着整个食物链的物质循环和能量流动，浮游植物的多样性与海洋生态系统的稳定性有着密切的联系。

Phytoplankton is the most important primary producer in the estuary ecosystem , and also a basic link of marine food chain . It influences on the material circulation and energy flow . Phytoplankton biodiversity is closely related to marine ecosystem stability .

鲨鱼已经在地球上存在了4亿年。它们在海洋的食物链中扮演着不可缺少的角色。

Sharks have been around for 400 million years and play an important role in the ocean 's food chain .

最危险的鱼是处于海洋上层食物链中最高级的食肉鱼，比如旗鱼和鲨鱼（见图表）。

The fish most at risk are predators high in the pelagic food chain , such as swordfish and sharks ( see chart ) .

然后其它细菌再将氮气送回陆地及海洋的食物链中，至此它最终形成氨基酸。

Then other bacteria fix that nitrogen gas back into food chains - on land and in the ocean - where it eventually finds its way into amino acids .

鱼类正在以塑料微粒为食，以为这是浮游生物或者其它食物，于是塑料就进入了海洋中的食物链。

The fish are consuming small particles of plastic thinking it is plankton or other food then the plastic enters the food chain of the ocean .

它所在的海域营养贫乏、温度高于正常的海水——大概比平均温度高4华氏度——正在扰乱海洋生物的食物链。
