海洋生态系统

理解海洋生态系统是一个相互关联的系统，其中生物（生产者、消费者、分解者）与非生物因素（温度、盐度、光照、洋流）相互作用，并且某一组成部分的变化会影响整个系统。

Understand ocean ecosystems as interconnected systems where living things (producers, consumers, decomposers) and non-living factors (temperature, salinity, light, currents) all interact, and that changes to one part affect the whole system

学习证据 / Evidence

• 描述海洋生态系统是生物部分与非生物部分相互作用的系统。
• 说出影响海洋生物的关键非生物因素：温度、盐度、光照和洋流。
• 解释某一因素（如温度）的变化如何在整个生态系统中产生连锁反应。

• Describe an ocean ecosystem as a system of living and non-living parts that interact
• Name key non-living factors that affect ocean life: temperature, salinity, light, currents
• Explain how a change in one factor (like temperature) cascades through the whole ecosystem

评估问题 / Assessment

{{name}}能否解释为什么海洋温度升高不仅仅影响一个物种——而是会改变整个生态系统，从食物网底部的浮游生物到顶端的鲸类？

Can {{name}} explain why warmer ocean temperatures don't just affect one species — they change the whole ecosystem, from the plankton at the bottom of the food web to the whales at the top?
