Use this poster to demonstrate the role of primary producers in the marine ecosystem food chain.
初级生产者合成阳光和营养，以形成食物链的基础。
该海报突出了浮游植物在海洋食物链中的作用。
浮游植物被主要消费者（海星，虾，浮游动物，蜗牛，鲸鱼，小鱼，水母）消费，这些消费者又被中等消费者（鱼类，鲸鱼，鲨鱼）消费。
During this process, the remaining dead bodies and waste is broken down by decomposers (crabs, coral, mollusks) which is then used by Primary Producers to begin the cycle again.
